How fast would a 147.5kg football player have to run to have the same momentum as a 126.2kg football player running at a speed of 5.9 m/s
Answer provided by our tutors
For this question, we will use the general equation momentum=mass times velocity (p=mv). We are given that their momentums are equal so we can write m1v1=m2v2, or:
147.5 kg (v) = 126.2 kg (5.9 m/s)
where v is what we are searching for. Solving for v, we get:
v=5.048 m/s
