Question

A body of mass m accelerates uniformly from rest to v 1 in time t 1 . The instantaneous power delivered to the body as a function of the t is, m ⁡ ν 1 t ⁡ t ⁡ 1, m ⁡ ν 1 2 t ⁡ t ⁡ 1 2, m ⁡ ν 1 t ⁡ 2 t ⁡ 1, m ⁡ ν 1 2 t ⁡ t ⁡ 1

Acceleration a = ν 1 t ⁡ 1 ∴ Velocity ( ν ) = 0 + a t ⁡ = ν 1 t ⁡ 1 t ⁡ Power P ⁡ = Force × velocity = m ⁡ a ν or P ⁡ = m ⁡ ( ν 1 t ⁡ 1 ) × ( ν 1 t ⁡ t ⁡ 1 ) = m ⁡ ν 1 2 t ⁡ t ⁡ 1 2
