How far is Romanoff above the ground when the jet crashes into the ground?

A runner accelerated from rest at x0 = 0m with a constant acceleration 2.0 m/s2 for 2.0 s and then kept running with his constant velocity for an additional 8.0 s. Assume that the runner moved in a straight line.

6. A hot-air balloon is descending at a rate of 2.3 m/s when a passenger drops a camera. If the camera is 41 m above the ground when it is dropped, (a) what is its velocity just before it lands? (b) how much time does it take for the camera to reach the ground? Let upward be the positive direction for this problem.

When last we left our friend Wile E. Coyote (SuperGenius), was peeling himself off a canyon wall and none the worse for wear. This time, he has obtained an Acme^ TM rocket-powered dragster with the AcmeTM Premium Parachute Braking System (patent pending)Starting from restthe dragster accelerates at a constant rate of 36.4 m/s ^ 2 for 14 seconds. At this point, the coyote realizes that he has passed the Road Runner and so he instantly cuts off the engine and deploys his braking system - which doesn't work. He therefore travels an additional distance of 1800 m at constant velocity until again becoming one with a canyon wall. Determine: (a) The total time for Wile E. Coyote's motion described above; on (b) The total distance covered by Wile E. Coyote's motion described above ; (c) The average velocity for Wile E. Coyote's motion described above.

1. The cheetah can reach a top speed of 114 km/h. while chasing its prey in a short sprint, a cheetah starts from rests and runs 45 min in a straight line, reaching a final speed of 72 km/h. a. Determine the cheetah's average acceleration during the short sprint, and b. Find its displacement at t= 3.5 s O 4.4m/s2, 27m O 5.6m/s2, 56m O 1.2m/s2, 15m

The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.40 s to a final velocity of 1.50 m/s, at which point the brakes are released. What was its initial speed (in m/s), just before the brakes were applied? What was its acceleration (in m/s2) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction with the sign of your answer.)

1:   Two trucks both cover a straight distance, d = 297 m, in time t = 11.5 s. Truck A moves at a constant velocity (vA). Truck B moves at a constant acceleration (aB), starting from an initial velocity of v0B = 5.9 m/s. Assume both trucks are moving in the positive x-direction.   Part (b)  What is the final velocity of Truck B?
