Question

Beth wants to maximize her chances of winning the bowling tournament so she tests several balls to find the best fit. She exerts the same 14 N of force to propell the bowling ball down the lane. Will a 3.2 kg, 3.6 kg, 4.1 kg, or 4.5 kg ball provides the fastest acceleration?

A) 3.2 kg ball
B) 3.6 kg ball
C) 4.1 kg ball
D) 4.5 kg ball

Answer 1

A) 3.2 kg ball

Step-by-step explanation:

To solve this problem we must apply Newton's second law of motion, and it states:

"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object."

`F=m*a`

Being:

F= net force

m=mass of the object

a= acceleration

As acceleration is inversely proportional to mass, we conclude that to have fastest acceleration Beth should use the lighter ball of 3.2Kg mass.
