A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 5.11 m/s. The car is a distance d away. The bear is 34.0 m behind the tourist and running at 7.01 m/s. Both the bear and the tourist are running with constant velocity. What is the maximum possible value for d in meters for the tourist reaches the car safely?
Motion is not absolute but relative. We are given the speed of bear and the tourist. We are also given the distance between them. We first find the relative velocity of bear wrt tourist. We then find the time when the bear just catches the tourist. We find the distance covered by tourist in this time. If this distance is equal to the distance of car from him, then he will be safe.

- An object is thrown straight up from the top of a building that is 31.2 m high. The object is thrown with a velocity of 16.4 m/s. At the same time the object is thrown upwards, a person runs along the ground with a constant speed of 3.4 m/s. When the object hits the ground, how far has the person gone in meters?A blue car travels down a straight road at a constant speed of 21.7 m/s. As they pass a red car, initially stopped on the side of the road, the red car speeds up at a rate of 2.12 m/s2. How much distance (in m) does the blue car travel before the red car overtakes the blue car?A rock is fired straight downward from the roof of a tall building using a slingshot. If the rock leaves the slingshot with a downward velocity of 11.2 m/s, and reaches the ground with a downward velocity of 34.7 m/s, how tall is the building? How long is the rock in the air, in seconds?
- In heavy rush-hour traffic, you drive in a straight line at 12 m/s for 1.5 minutes, then you have to stop for 3.5 minutes, and finally, you drive at 15 m/s for another 2.5 minutes. Plot a position-versus-time graph for this motion. Your plot should extend from t = 0 minutes to t = 7.5 minutes. Assume x=0 and t=0 at the start of your motion.A cannonball is fired at 171 (m/s), straight up in the air, by accident. Quickly realizing the error, the commanding officer orders the gunners to fire another cannonball straight up to hit the one coming down. In order to be safe, the two cannon balls must explode at a given hight of 636 (m). What is the maximum time (in seconds) the second cannonball can be fired after the first, such that the two cannaballs collide, exploding safely above the regiment? (s) How fast (velocity) will the first cannon ball be traveling just before the collision? (m/s) How fast (velocity) will the second cannon ball be traveling just before the collision? (m/s)Two kids are racing towards a toy somewhere between them. Albert has 3.90 times further to run than Betty. Albert is to the West of the toy and Betty is to the East of the toy. Albert runs at a constant speed of 1.60 m/s. It takes him 2.90 s to reach the toy.How far did Albert run to reach the toy?
- A truck, stolen by Dora the Explorer is initially stopped 10.0 m from the base of a building. Peppa pig is 22.0 m above the ground on the balcony of her office building. The truck begins to accelerate towards the building. One second after the truck moves, Peppa pig jumps off the balcony. Peppa pig, in an attempt to stop Dora the Explorer, times her fall perfectly and lands on the truck, which is 3.0 meters above the ground. What was the acceleration of the truck and its final velocity (assume constant acceleration)?A swimmer took a running leap off a high-diving platform. The swimmer was running at 2.8 m/s and hit the water 2.6 seconds later. a) How high was the platform, and b) how far from the edge of the platform did the swimmer hit the water? Ignore wind resistance.A Lockheed Martin F-35 Lightning II jet takes off from an aircraft carrier with a runway length of 107 m and a takeoff speed 77 m/s at the end of the runway. Jets are catapulted into airspace from the deck of an aircraft carrier with two sources of propulsion: the jet propulsion and the catapult. At the point of leaving the deck of the aircraft carrier, the F-35's acceleration decreases to a constant acceleration of 4.8 m/s2 at 23° with respect to the horizontal. (Assume that the F-35's initial direction along the deck of the aircraft carrier is the +x-direction and that the +y-direction is up.) What is its velocity and speed at this time? (Enter your answers in m/s.) v(5.4 s)= (?î +?ĵ) v(5.4 s)= ? m/s How far (in m) has it traveled horizontally?
- Question 8. You are traveling in a convertible with the top down. The car is moving at a constant velocity of 20.4 m/s, due east along flat ground. You throw a tomato straight upward at a speed of 5.68 m/s. How far has the car moved when you get a chance to catch the tomato? Ans: 23.65 mA lemon is launched upwards at 28.0 m/s. It goes up, and on the way down it strikes the top of a 35.2 m tall light tower. With what velocity does it strike the light tower? What is its displacement 4.15 seconds after it is launched?Chapter 02, Problem 034 GO Z Your answer is partially correct. Try again. In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at x, = 0 and the green car is at x, = 223 m. If the red car has a constant velocity of 23.0 km/h, the cars pass each other at x = 44.8 m. On the other hand, if the red car has a constant velocity of 46.0 km/h, they pass each other at x = 76.2 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs. Green car Red car (a) Number-19.993 Unit m/s^2 (b) Number |-1.544 Unit m/s^2 Click if you would like to Show Work for this question: Open Show Work
