You are arguing over a cell phone while trailing an unmarked police car by 27.0 m. Both your car and the police car are traveling at 100 km/h. Your argument diverts your attention from the police car for 2.30 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.30 s, the police officer begins emergency braking at 5.00 m/s². (a) What is the separation between the two cars when your attention finally returns? x m (b) Suppose that you take another 0.400 s to realize your danger and begin braking. If you too brake at 5.00 m/s?, what is your speed when you hit the police car? km/h

The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 2.20 m above the floor. The ball hits the floor 0.335 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 39.2 m/s^2 19.6 m/s^2 29.4 m/s^2 62.7 m/s^2

A man flies a small airplane from Fargo to Bismarck, North Dakota a distance of 180 miles. Because he is flying into --- a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 hour 12 minutes. What is his speed in still air, and how fast is the wind blowing? Your answer is his speed equals the wind speed equals
The clark freeport zone and philippine international hot air balloon foundation incorporation organizers the 18th clark philippines hot air balloons Fiesta last February 21-24, 2013. During the event a bag drop from the hot air balloon reaches the ground in 20 seconds. Determine the height of the hot air balloon (a) if it is at rest in the air and (b) if it is ascending with a speed of 49 m/s when the bag is dropped. ANS. (a) 1.96x10³m (b) -9.8x10²m
A typical jetliner lands at a speed of 160 mi/h and decelerates at the rate of (10.0 mi/h)/s. If the plane travels at a constant speed of 160 mi/h for 1.00 s after landing before applying the brakes, what is the total displacement of the aircraft between touchdown on the runway and coming to rest?
As a city planner, you receive complaints from local residents about the safety of nearby roads and streets. One complaint concerns a stop sign at the corner of Pine Street and 1st Street. Residents complain that the speed limit in the area (55 mph) is too high to allow vehicles to stop in time. Under normal conditions this is not a problem, but when fog rolls in visibility can reduce to only 155 ft. Since fog is a common occurrence in this region, you decide to investigate. The state highway department states that the effective coefficient of friction between a rolling wheel and asphalt ranges between 0.689 and 0.770, whereas the effective coefficient of friction between a skidding (locked) wheel and asphalt ranges between 0.450 and 0.617. Vehicles of all types travel on the road, from small VW bugs weighing 1210 lb to large trucks weighing 8640 lb. Considering that some drivers will brake properly when slowing down and others will skid to stop, calculate the minimum and maximum…
A treasure hunter follows a map moving 25 km [N], 37 km [W 37 degrees S], 63 km [E 65 degrees S] and finally 15 km [N 17 degrees E]. If his average for the entire trip was 45 km/hr, calculate: a. The total time for the trip; and b. The average velocity of the trip
An object's position in the as a function of time obeys the equation; x(t) = 14.2/t2.17 + 5.1t3 where all constants have proper SI Units. What is the speed of the object in the x direction at t = 1.93 seconds?
An initially motionless test car is accelerated uniformly to 135 km/hr in 8.08 seconds before striking a simulated deer. The car is in contact with the faux fawn for seconds, after which the car is measured to be traveling at 87.5 km/hr. What is the magnitude of the average acceleration of the car during the collision?
