The 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:
- \(\frac{1}{2} m \frac{v}{t_{1}} t^{2}\)
- \(m \frac{v}{f_{1}} t^{2}\)
- \(\frac{1}{2}\left(\frac{m v}{t_{1}}\right)^{2} t^{2}\)
- \(\frac{1}{2} m \frac{v^{2}}{t_{1}^{2}} t^{2}\)
Answer
(D) 1 2 m v^ 2 t_ 1 ^ 2 t^ 2
