Answer 1

Impulse:

Impulse = Change In Momentum

So J = M* |V2 - V1|           [J is the Symbol of Impulse]

J = 0.25* |-2-2|

J = 0.25 * 4            [Because There is a Mod Sign || ]

J = 1 kgm/s

Average Force :

Ball Mass = 250 g or 0.25 Kg

Initial Velocity = 2 m/s

Final Velocity = 2 m/s

T = 10^-3

By Using

v = u +at

a = 4*10^3 or 4000 m/s^2

Now Using F = ma to calculate the Force...

We get

F = 0.25*4000

F = 1000N
