Question

Select the correct answer. the leaning tower of pisa is about 56 meters tall. a ball released from the top takes 3.4 seconds to reach the ground. the final velocity of the ball before it hits the ground is 33 meters/second. assuming that the ball experienced a constant acceleration throughout this descent, calculate the magnitude of the acceleration. a. 9.8 meters/second2 b. 9.7 meters/second2 c. 112.2 meters/second2 d. 0.10 meters/second2

1. The correct option is b. 9.7 meters/second².
The magnitude of the acceleration of the falling ball is 9.7 meters/second².

### What is acceleration?

Acceleration is the rate for which velocity changes over time, both in terms of speed and direction. A point or object travelling in a straight path gets accelerated if it accelerates or decelerates.
The final velocity of a falling ball, v = 33 m/s
The ball’s initial velocity, u= 0 m/s
The time it required for the ball to arrive at the ground, t = 3.4 seconds
The ball’s acceleration during the fall Equals ‘a’.
The formula for acceleration is;
acceleration = (final velocity – initial velocity)/time
Substituting the values in the formula;
a = (33 – 0)/3.4
a = 9.7
Therefore, the rate of acceleration of the falling ball is 9.7 m/s².
