A 1kg body is subjected to a single force
b)Linear momentum before and after the force is exerted.
Δt = 5 s
m = 1 kg
Linear momentum before applying the force p0 = ?
Linear momentum after applying the force p = ?
We know impulse of a force is calculated by multiplying that force by the time applied, so:
By using the linear momentum definition we can calculate the moment before applying the force:
Since the impulse is equal to the growth of the linear momentum when applying the force, and the growth is the substraction of momentum the body has before and after applying the force:
