Chapter 2, Problem 64EAP
Bob is driving the getaway car after the big bank robbery. He’s going 50 m/s when his headlights suddenly reveal a nail strip that the cops have placed across the road 150 m in front of him. If Bob can stop in Lime, he can throw the car into reverse and escape. But if he crosses the nail strip, all his tires will go flat and he will be caught. Bob’s reaction time before he can hit the brakes is 0.60s, and his car’s maximum deceleration is 10 m/s2. Does Bob stop before or after the nail strip? By what distance?

I had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?
As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 37.0 m/sm/s.How fast is the watermelon going when it passes Superman?
A hot-air balloon has just lifted off and is rising at the constant rate of 2.5 m/s . Suddenly one of the passengers realizes she has left her camera on the ground. A friend picks it up and tosses it straight upward with an initial speed of 14 m/s .
If the passenger is 2.5 m above her friend when the camera is tossed, how high is she when the camera reaches her?

To get Vin Diesel's attention on TicTok she decides to redo one of his movie stunts. Songlu rents a Porsche 911 convertible, pays the extra $10 per day for insurance, and then drives to Big Bear. When she gets there, Songlu puts on her parachute and drives at a speed of 215 mph (96.1 m/s) off of a 450 m tall cliff, jumping out mid air so she can use her parachute on the way down. How far does Rubbab's rented Porsche 911 land from the base of the cliff? O 832 m O 614 m O 1,230 m O 921 marrow_forwardYou are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.00 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it.

- In the children's book Nuts to You, a young squirrel named Jed is snatched up by a hawk. While in the air Jed manages to go limp, slip through the hawk's talons and fall to the forest floor. The hawk travels horizontally at a speed of 4.86m/s . (You may neglect any effects of air resistance as you answer the following questions). One second after being released, what is the y-component of Jed's velocity?arrow_forwardA Boeing 747 "Jumbo Jet" has a length of 64.5 m. The runway on which the plane lands intersects another runway. The width of the intersection is 24.8 m. The plane decelerates through the intersection at a rate of 5.56 m/s2 and clears it with a final speed of 43.1 m/s. How much time is needed for the plane to clear the intersection?arrow_forwardA sailor is enjoying a nice day on his sailboat, sailing west with the wind at constant velocity. At one point the sailor spots an anchored buoy some distance to the east of the boat, and turns on his motor to head towards it. The boat kept gliding to the west for some distance before turning around and heading eastward. The boat was traveling initially with velocity v = -6.0i m/s and it took the the boat 2.0 s to turn around. What is the velocity of the boat, 5.0 s after the motor is turned on?

- A hare and a tortoise are having a race along a 2.0km track. The tortoise sets off at a constant speed of 1.6 m/s. The hare is confident that they can win, so first do 1000 meters at 5 m/s turns around and sees the hare and so stops and falls asleep for 10 mins. The hare wakes up and then sees the tortoise too close so speeds up again at 5m/s for another 500 meters after which the Hare again decides to sleep for 5 mins being so are in front. The Hare wakes up and sees the Tortoise! He dashes for the finish another 500 meters away at 8 m/s. To no avail as the story goes. By how much did the Tortoise win?arrow_forwardThe infamous chicken is dashing toward home plate with a speed of 5.7 m/s when he decides to hit the dirt. The chicken slides for 1.2 s, just reaching the plate as he stops (safe, of course). (a) What are the magnitude and direction of the chicken’s acceleration? (b) How far did the chicken slide?arrow_forwardAn Osprey can fly horizontally (not diving) at a maximum speed of 70.0 km/hr. The bird takes off from rest at the edge of a cliff, heading east, and accelerates at a rate of 1.21 m/s2. The osprey can decelerate at higher rate of 2.43 m/s2. The Osprey can reach top speeds of about 84 mph. When doing so, it does not flap its wings. Rather, it relies on its gravitational force to accelerate it downwards. a. Assuming that it starts from rest, and assuming that drag forces are slim, how long will it take for the osprey to reach its top speed? b. How far does it travel during this time? c. Near the top speed, drag forces become important, and in fact the terminal velocity is determined by the drag force. Assuming that the osprey's body can be modeled as a cylinder, with its cross-sectional area equal to that of a circle with radius of 10 cm, what is the coefficient of drag C for a hawk?arrow_forward
- While moving from her third-storey apartment, a university student decides to lower her couch through her window using ropes. During the process, the ropes snap and the couch, which is 12.0 m above the ground, falls to the ground below. Her friends, who are both 1.50 m tall, notice the accident when the couch is directly above them. Determine the time they have to get out of the way.arrow_forwardCould I have help with this question?arrow_forwardA hare and a tortoise compete in a race over a course 1.00 km long. The tortoise craws straight and steadily at its maximum speed of 0.200 m/s toward the finish line. The hare runs at its maximum speed 8.00 m/s toward the goal for 0.800 km and then stops to tease the the tortoise. How close to the goal can the hare let the tortoise wins in a photo finish? Assume that, when moving, both animals move steadily at their respective maximum speeds. Pls include figures and fbd.arrow_forward
