The height reached by the ball is 78.4 m.
What is Height?
Height can be defined as the vertical distance between two points.
To calculate the height reached by the ball, we use the formula below.
Formula:
- H = ut+gt²/2............ Equation 1
Where:
- H = Height reached by the ball
- t = Time taken to reach the height
- u = Initial velocity
- g = acceleration due to gravity
From the question,
Given:
- t = 4 s
- g = 9.8 m/s²
- u = 0 m/s
Substitute these values into equation 1
- H = (0×4)+(9.8×4²)/2
- H = 9.8×8
- H = 78.4 m
Hence, the height reached by the ball is 78.4 m.
