Answer 1

Answer:

1. Cricket ball

2. 20 m/s

Explanation:

1. The inertia of a body depends upon the mass of a body.

  Greater the mass, higher is the inertia.

 Since a cricket ball is heavier than a rubber ball, therefore it will have more inertia.

2. Initial velocity of object (u) = 0 m/s

  Acceleration ( a) = 10 m/$s^2$

  Time (t) = 2 s

Using the 1st equation of motion-

v= u + at

v= 0 + 10 × 2 m/s

v = 20 m/s
