Question

A force of 400N on a body for time interval of 10ms. Calculate the impulse?

Answer 1

Explanation:

Impulse, or change in momentum, equals the average net external force multiplied by the time this force acts: Δp = FnetΔt. Forces are usually not constant over a period of time

f=ma

400=10×a

a=-400

------

10

a=-40m/s2

Answer 2

Answer:

6

because any four character have 6
