A car is initially moving at 20 m/s. The car then accelerates at a rate of 5 m/s2. How fast will the car be moving after 400 meters?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
