A car initially at rest picks up a velocity of 90km/h through a distance of 30 m find the a)acceleration of the car b) time in which it picks up the velocity

we need to know the time interval during which the force acts. impulse of force = momentum change

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

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
