A gold ball has a mass of 45g. In a speed test, a golf ball was driven from rest to a velocity of 90m/s.

a) If the time taken for the golf ball to reach this velocity was 0.0005 seconds. What acceleration was this?

b) What forces was applied to the golf ball?

Answer:

1)

Acceleration (a)=change in velocity/ change in time

Velocity (v)=90m/s

Time=0.0005s

a=90/0.0005

The acceleration =180000m/s^2 or 180km/s^2

Force = mass x acceleration

m=40g= 0.04kg

F= 0.04x 180000

F= 7200N or 7.2kN
