Expert Solution

Step 1

Given data:

Mass of the baseball is,

m_b = 0.2 kg

Mass of the cat is,

m_c =6 kg

Mass of the sled is,

m_s = 10 kg

Acceleration of the baseball is,

a_b = 40 m/s²

Acceleration of the cat is,

a_c = 1.5 m/s²

The net force on the sled is,

F_s = 5 N

Formula used:

According to Newton's second law of motion, force is,

$F = m a$

Where,

F- Force acting on an object

a- Acceleration of an object

m- Mass of an object
