Find the initial velocity of a fighter jet that
accelerates at 50m/s to
a final velocity of
330m/s in just 1.5
seconds.

a = dv/t = (330-x)/1.5 =50

x= 330-75 = 255 m/s

Intial velocity 255 m/s

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
