A bob of mass m accelerates uniformly from rest to v1 in time \(t_{1}\). As a function of t, the instantaneous power delivered to the body is

- \(\frac{m v_{1} t}{t_{2}}\)
- \(\frac{m v_{1} t}{t_{1}}\)
- \(\frac{m v_{1} t^{2}}{t_{1}}\)
- \(\frac{m v_{1}^{2} t}{t_{1}^{2}}\)
Answer
(D) m v_ 1 ^ 2 t t_ 1 ^ 2
