Question

1. Which object has the least momentum?

Object A: m = 1kg, v = 100m/s

Object B: m = 10kg, v = 12m/s

Object C: m = 0.5kg, v = 1000m/s

Object D: m = 100kg, v = 2m/s

2. If a 54 Ns impulse (recall, impulse is force*time, so it is measured in Newtons*seconds) is given to a 6kg object, then the trasnfer of momentum is.

a. 6 Ns

b. 9 Ns

c. 54 Ns

d. 324 Ns

Answer 1

0 Momentum of object p=mv is given by PA= 1kgx 100 m) S = 100 kgmis PB = 10 kg x 12 m/s 120 kgm is pe = o.skgx 1000mls 500 kg mis PD = 100kg x amis = 200 kg mis . Object A has least momenten Impule = change in momentem Ap = 54 N.S
