Given: 110-kg football player running at 8.0 m/s, hard-thrown 0.410-kg football that has a speed of 25.0m/s.
To find: Compare the momentum of both.
Solution:
- Now we have given mass of football player as 110 kg and velocity as 8 m/s.
- So momentum 1 = m1v1
momentum 1 = 110 x 8
momentum 1 = 880 kg m/s
- Also, we have given mass of hardthrown as 0.410 kg and velocity as 25 m/s.
- So momentum 2 = m2v2
momentum 2 = 0.410 x 25
momentum 2 = 10.25 kg m/s
- Now comparing both, we get:
momentum 1 / momentum 2 = 880 kg m/s / 10.25 kg m/s
momentum 1 / momentum 2 ≈ 89 times.
Answer:
So the ratio of momentum 1 / momentum 2 comes out to be 89 times.
