Without friction, what is the mass of an ball accelerating at 1.8 m/sec2 to which an an unbalanced force of 42 Newtons has been applied?
A 75.60 kg
B 00.04 kg
C 23.33 kg
D 43.80 kg

Explanation:

The mass of the object can be found by using the formula

f is the force

a is the acceleration

From the question we have

We have the final answer as

Hope this helps you

Explanation:

According to Newton's Second Law of Motion, force is the product of mass and acceleration.

The mass of the ball is unknown. The ball is accelerating at 1.8 meters per second squared. An unbalanced force of 42 Newtons is applied to the ball.

Convert the units of force. 1 Newton is equal to 1 kilogram meter per second squared, so our answer of 42 Newtons is equal to 42 kg*m/s².

Substitute the values into the formula.

We are solving for the mass, so we must isolate the variable m. It is being multiplied by 1.8 meters per second squared. The inverse operation of multiplication is division. Divide both sides by 1.8 m/s².

The units of meters per second squared cancel.

Round to the hundredth place. The 3 in the thousandth place tells us to leave the 3 in the hundredth place.

The mass of the ball is approximately 23.33 kilograms.
