What is the impulse received by a ball of mass 0.5 kg that changes its velocity by 28 m s-1? Give your answer to the nearest whole number.

Question

BlackTom AI · Accepted Answer

To find the impulse delivered to the ball, recall that impulse J equals the change in momentum: J = Δp = m Δv.
The mass given is m = 0.5 kg, and the velocity change is Δv = 28 m/s.
Multiply mass by the velocity change: J = 0.5 kg × 28 m/s = 14 kg·m/s.
Since impulse has units of momentum, this can be written as 14 N·s (newton-seconds).
The problem asks for the value to the nearest whole number, and 14 is already an integer, so the answer is 14.
