Question

Two balls identical in shape and size are acted upon by equal forces which cause them to move on a horizontal surface. The acceleration of the second ball is thrice of that of the first. What is the ratio of the mass of the second to the first

Answer 1

Explanation:

Let the mass of first block =m

1

acceleration of block of mass m

1

=a

Let the mass of second block =m

2

acceleration of block of mass m

2

=5a

Force=mass×acceleration

Since forces are equal,

m

1

,a=m

2

5a

m

2

m

1

=

a

5a

=5

m

1

m

2

=
