Answer:

1. 0.6 kg.m/s

2. 72 kg

3. Vf = 5.25 m/s

4. The car

Explanation:

1. p = mv

p = (1.2 kg)(0.5 m/s)

p = 0.6 kg.m/s

2. m = p/v

m = 360/5

m = 72 kg

3. pi = pf

30(7) + u = (30+10)Vf

Vf = 5.25 m/s

4. p = mv

p = (1000 kg)(1 m/s)

p = 1000 kg.m/s

p = mv

p = (70 kg)(8 m/s)

p = 560 kg.m/s

Hope It Helps :)
