Question

A construction company uses a crane to lift a wrecking ball2000kg the crane can cause the wrecking ball to speed up from rest to 0.1m/s in 0.2 second what is the acceleration of the wrecking ball during this time

Answer 1

a = dv/dt = (0.1 - 0)/0.2 = 0.5 m/s^2

Answer 2

V = Vo + a*t = 0.1
0 + a * 0.2 = 0.1,
a = 0.5 m/s^2.
