Answer:
110 kg
Explanation:
The momentum of the Malcom+motorcycle system is given by:
[tex]p=(m+M)v[/tex]
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:
[tex]m=\frac{p}{v}-M=\frac{6000 kg m/s}{20 m/s}-190 kg=110 kg[/tex]
