Question

The impact time for a particular collision is 3.0 x 10^-3 seconds and the impulse in the collision is 0.30 newton seconds. What is the force of the collision?
A.) 25 Newton’s
B.) 50 Newton’s
C.) 1.0 x 10^2 Newton’s

Answer 1

Answer

C.) 1.0 x 10^2 Newton’s

Explanation

The Newton's second law of motion states that, the rate of change of momentum is proportional to the force producing it.

∴ F = (mv- mu)/t

  Ft = mv - mu.

The quantity Ft is called the  impulse.

Ft =  0.30 Newton seconds

but t = 3.0 x 10⁻³ seconds

Ft =  0.30 Ns

F × 3.0 x 10⁻³ =  0.30 Ns

F =  0.30 / (3.0 x 10⁻³)

  = 100 N

  Answer =  C.) 1.0 x 10^2 Newton’s
