Question

at what speed do a bicycle and its rider, with a combined mass of 80 kg k g , have the same momentum as a 1300 kg k g car traveling at 6.0 m/s m / s ? express your answer to two significant figures and include the appropriate units.

Answer 1

97.5 m/s

Step-by-step explanation:

Get:

Mc=1300 Kg - Mass of car

Vc = 6 m/s - Velocity of car

Mb = 80 Kg - Mass of bicycle with rider

Find:

Vb? - Velocity of bicycle

Solution:

p=VbMb=McVc=1300*6=7800 Kg

Vb=p/Mb=7800/80=97.5 m/s
