Which of the following pieces of equipment might be if you wanted to measure acceleration?
a. stopwatch
b. spring scale
c. thermometer
d. triple beam balance

d = -11.025 m

Explanation:

Given that,

An egg is dropped from a treehouse and takes 1.5 seconds to reach the ground. We need to find the egg's displacement. It can be calculated using second equation of motion as follows :

u is initial speed, the initial speed of egg is 0 as it was at rest initially.

a = -g (as the stone is coming downward direction)

t is time.

si is egg's displacement

-ve sign shows the displacement of the egg in opposite direction of its motion and its magnitude is 11.025 meters.
