It would be appreciated if all questions were answered and have shown work. :)
2 answers:
1)
P = mv
P=75 (18) = 1350 kg-m/s
2)
0.25 v= 0.05 (500)
V= 100 m/s
3)
∆ mv = F∆t
55(20) =F(0.5)
1. The formula for momentum is:
p = mv
p =75(18) = 1350 kg-m/s
2. We equate the momentum of the two objects
0.25 v = 0.05 (500)
v = 100 m/s
3. We use the formula for impulse:
Δmv = FΔt
55(20) = F(0.5)
F = 2200 N
