Acar accelerates at 4 m/s2 for 5 seconds. the direction of its acceleration is due east (east = positive direction). if its initial velocity was 7 m/s, also due east, what is its final velocity? round your answer to the nearest meter per second.

If you held a stone over the mouth of a well and then let it go , what would happen to the stone? explain your answer.

Give an example for each of the following situations: 1) negative acceleration, but positive velocity 2) positive acceleration and positive velocity 3) positive acceleration, but negative velocity 4) negative acceleration and negative velocity 5) positive velocity and no acceleration

A55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. knowing that the plane has a speed of 550 km/h at point a, and the pilot experiences weightlessness at point c (i.e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point b.
