# Pre-AS Physics summer work help please watch

1. Hi all,

I was given this question as a part of my summer work to get me prepared for AS Physics. I couldn't understand how to go about starting the question, could someone help me please?

"The time taken for a ball to reach the ground was measured using data logging equipment. The results of the experiment are shown below:

Height (m): 0.50, 1, 1.5, 2, 2.5, 3, 3.5, 4
(corresponding) Time taken (t/s): 0.32, 0.45, 0.55, 0.64, 0.71, 0.78, 0.84, 0.90

The relationship between h and t is given by the following equation:

h = 0.5gt^2

What would you need to plot to get a straight line?

Plot this data and calculate the value for g. Show how you have calculated a value for g."

I have tried an array of values for h, g and even t. But to no avail.

Thank you very much.
2. Try to plot h vs g and h vs t^2 and see what you get.
