4 To determine the acceleration of free fall g, a ball is dropped from rest from a point vertically
above a light gate.

The ball has a diameter of 5.0 cm. It is dropped at time t = 0.

The light gate output shows that the ball passes through the gate between times t = 0.10 s and
t = 0.14 s.

The graph shows the output from the light gate.

Air resistance has negligible effect on the motion of the ball.

What is the value of g in m s–2 from these measurements?

A 8.93

B 9.81

C 10.4

D 12.5
