Question: An object is dropped from the top of a building and it hits the ground in 3 seconds. What is the height of the building?


Explanation:

Given:
Initial Velocity (u) = 0 m/s²
Acceleration Due To Gravity (g) = 10 m/s²
Time Taken (t) = 3 seconds

Now, to find the height of the building we will apply the second equation of motion.
h = ut + \frac{1}{2}gt²
h = 0(3) + \frac{1}{2}(10)(3)²
h = 0 + 5 x 3 x 3
h = 45 m

Answer: The height of the building is 45 meters.
