Question
A ball of mass 1 kg drops velocity on to the floor with a speed of 25 m/s. It rebounds with an initial velocity of 10 m/s. What impulse acts on the context ?
Options
A.35 kg m/s downwards
B.35 kg m/s upwards
C.30 kg m/s downwards
D.30 kg m/s upwards
Solution
Impulse
= pf - pi = 1 × 10 - 1 × (-25) = 35 kg m/s (↑)
= pf - pi = 1 × 10 - 1 × (-25) = 35 kg m/s (↑)
