Question

If a man has a mass of 74 kilograms runs 800 meters in 150 seconds,what is

his average momentum?

Answer 1

Answer:3.94 kg*m/s

Step-by-step explanation:

Use eqation for momentum: p=m*V

m-mass

V-speed

Speed is calculated using: V=S/t

S-distance (800m)

t-time(150 s)

V=S/t

V=800m/150s

V=5.33m/s

Now calculate momentum:

p=m*V

p=74kg*5.33m/s

p=3.94kg*m/s
