Question 45

An engineer is testing a prototype electromagnetic launcher. A sled is accelerated from rest along a straight horizontal track of length, ddd, in a time, ttt.

She records the following measurements:

  • Track length, d=5.80 md = 5.80\text{ m}d=5.80 m
  • Time, t=0.48 st = 0.48\text{ s}t=0.48 s

Calculate the value of the constant acceleration, aaa, of the sled from these measurements.

Use the equation:

a=2dt2 a = \frac{2d}{t^2} a=t22d​
