A Body Is Initially At Rest. It Undergoes One-dimensional Motion With Constant Acceleration. The Power Delivered To It At Time T Is Proportional To


\(u = \frac{0m}{s}\)

a = constant acceleration

Power delivered P = Fv—-[1]

According to the first equation of motion, v = u + at

v = 0 + at = at

Force F = m * a

From equation —-[1], we get

P = ma * at

\(P = m * a^{2} t\)

P is proportional to t

Therefore, the power delivered is directly proportional to the time t.
