Question

A bowling ball rolled with a force of 15 N accelerates at a rate of 3 m/sec2; a second ball

rolled with the same force accelerates 4 m/sec2. What are the masses of the two balls?​

Answer 1

F=ma

1st ball

15=m*3

15/3=m

m=5kg

2nd ball

f=ma

15=m*4

m=15/4

=3.7

Answer 2

The masses of the two balls is 5 kg and 3.75 kg respectively.

Explanation:

Given that,

Force acting on a bowling ball, F = 15 N

Acceleration of the first ball, $a_1=3\ m/s^2$

Acceleration of the second ball, $a_2=4\ m/s^2$

We need to find the masses of two balls.

We know that the force is given by the formula as follows :

$F=ma$

For the first ball,

$F=m_1a_1\\\\m_1=\dfrac{F}{a_1}\\\\m_1=\dfrac{15\ N}{3\ m/s^2}\\\\m_1=5\ kg$

For the second ball,

$F=m_2a_2\\\\m_2=\dfrac{F}{a_2}\\\\m_2=\dfrac{15\ N}{4\ m/s^2}\\\\m_2=3.75\ kg$

So, the masses of the two balls is 5 kg and 3.75 kg respectively.
