A 2-kilogram body is initially traveling at a velocity of 40 meters per second east. If a constant force of 10 newtons due east is
applied to the body for 5 seconds, the final speed of the body is
(A) 15 m/s
(8) 25 m/s
(C) 65 m/s
(D) 130 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

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

truck y has a greater velocity than truck x.
