Question

A rolling ball with a mass of 1.01 kg crashes into a wall. The wall exerts a force of 2.40 Newtons and stops the ball. What was the magnitude of the acceleration of the ball at the time of the crash?

Answer 1

Answer:

Acceleration, a = 2.38m/s²

Explanation:

Given the following data;

Mass = 1.01 kg

Force = 2.4N

To find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

$F = ma$

Where;

• F represents force.

• m represents the mass of an object.

• a represents acceleration.

Making acceleration (a) the subject, we have;

$Acceleration, a = \frac{F}{m}$

Substituting into the equation, we have;

$Acceleration, a = \frac{2.4}{1.01}$

Acceleration, a = 2.38m/s²

Therefore, the magnitude of the acceleration of the ball at the time of the crash is 2.38 meters per seconds square.
