Work done in time t on a body of mass m which is accelerated from rest to a speed v in time t1 as a function of time t is given by

1. Work done in time t on a body of mass m, which is accelerated from rest to a speed v in time t₁, as a function of time t is given by:

A) \( W(t) = \frac{1}{2} m \left( \frac{v}{t_1} \right)^2 t^2 \)

B) \( W(t) = m \left( \frac{v}{t_1} \right) t \)

C) \( W(t) = \frac{1}{2} m v^2 t \)

... Answer is A)
