The impulse provided to the ball is equal to the change in momentum of the ball.
According to Newton's second law, The rate of change of momentum is directly proportional to the force applied. Hence, the equation can be written as:
Δp = F × t
Δp = change in momentum = Impulse
F = Force
t = time for which the force is applied
Now. if the force is doubled and the time remains same.
F(new) = 2F
t = t
Δp (new) = 2F × t
Δp (new) = 2 Δp (old)
Hence, the impulse gets doubled
Option C is correct.
