Acar accelerates from rest to a velocity of 5 meters/second in 4 seconds. what is its average acceleration over this period of time? a: its acceleration is 1.25 meters/second. b: its acceleration is 5 meters/second. c: its acceleration is 0.8 meters/second. d: its acceleration is 1.25 meters/second^2. e: its acceleration is 20 meters.

A10.0 kg cart and a 15kg cart are locked together with a compressed spring between them. they are then released so that the spring pushes the two carts apart. the 10.0 kg cart is moving at 4.5 m/s afterward. how fast is the 15kg cart moving? 3.0 m/s 2.0 m/s 4.5 m/s 5.0 m/s

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
