A 3 kg object is moving at 8 m/s. How much will its momentum be if the velocity is doubled?
Answer (1)
Momentum (p) is calculated as:p = m × vwhere:m = mass (3 kg)v = velocity (8 m/s, then doubled to 16 m/s)Initial momentum:p_initial = 3 kg × 8 m/s= 24 kg·m/sAfter doubling the velocity:p_final = 3 kg × 16 m/s= 48 kg·m/sThe final answer is:48 kg·m/s
