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 o
1 answer:
Answer:
110 kg
Explanation:
The momentum of the Malcom+motorcycle system is given by:
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:

From the question we are told that
The amount of Radiation received by an average american is
The source of the radiation is
Generally
Therefore
Also
Therefore
An Average american weighs 88.7 kg
The total energy received is mathematically evaluated as
Cross-multiplying and making x the subject
Therefore the total energy deposited is
The approximate number of decays this represent is mathematically evaluated as
