Question

malcom is doing a wheely on his motorcycle and moving at 20 m/s with a momentum of 6000 kg m/s when he lays her down. The mass of the motorcycle is 190 kg. What is the mass of Malcom?

Answer 1

Answer:

110 kg

Explanation:

The momentum of the Malcom+motorcycle system is given by:

$p=(m+M)v$

where

(m+M) is the total mass of the system, with

m = mass of Malcom

M = 190 kg (mass of the motorcycle)

v = 20 m/s velocity

Since we know the momentum:

p = 6000 kg m/s

We can re-arrange the equation to find the mass of Malcom:

$m=\frac{p}{v}-M=\frac{6000 kg m/s}{20 m/s}-190 kg=110 kg$
