Question

A golf club hits a 0.0459 kg golf ball
at rest. Afterwards the ball leaves
at 63.9 m/s. What impulse was
given to the ball?
(Unit = kg*m/s)​

Answer 1

Answer:

2.933 kg m/s

Explanation:

impulse = change in momentum

impulse = mass ( final velocity - initial velocity )

              = 0.0459 ( 63.9 - 0 )

               = 0.0459 × 63.9

                = 2.93301 kg m/s

or              = 2.933 kg m/s up to 4 significant figures
