Question

A golf ball with a mass of 43.5 g can be blasted from rest to a speed of 66.0 m/s during impact with a club head. Assume that the impact lasts only about 0.970 ms. Calculate the change in momentum of the ball.

Tries 0/3

Calculate the average force applied.

Answer 1

Solution:

Part (a) :calculating change in momentum

Change in momentum = =.... (1)

m = mass of ball=43.5 g=0.0435 kg

= change in velocity =66.0 m/s - 0 =66.0 m/s.. (initial velocity is "0" as ball started from rest.)

putting the values in equation (1)

.... Answer

Part (b) :Calculating average force applied.

Average force applied =F =

time of impact=0.970 ms =

Therefore

If rounded to 3 significant figures (all the given values have 3 significant figures)

F = 2960 N..... Answer
