Question

Yoshi then tested their momentum and time of collision and had the same change in momentum (20 kg m/s) but at his time was only 0.5 seconds. What was Yoshi's force?

Answer 1

Yoshi exerted a force of 40 Newtons, calculated by dividing the change in momentum (20 kg m/s) by the time of collision (0.5 seconds).

Step-by-step explanation:

The question is asking us to calculate the force exerted by Yoshi, given a change in momentum over a time period. The formula for force (F) in physics, derived from Newton's second law of motion, is F = Δp / t, where Δp is the change in momentum and t is the time taken for that change to occur. Here, Yoshi has a change in momentum of 20 kg m/s over 0.5 seconds.

F = Δp / t
F = 20 kg m/s / 0.5 s
F = 40 N

Therefore, the force Yoshi exerted is 40 Newtons (N).
