1. Homework Statement
According to Newtonian mechanics the momentum of the bus in the preceding problem is p= mv. According to relativity, p = gamma*mv. How does the actual momentum of the bus moving at .99c compare with the momentum it would have if classical mechanics were valid?

*Note*
The previous problem only states a bus and has nothing to do with the question

2. Homework Equations
Classical
p = mv

Special
p=gamma*mv

3. The Attempt at a Solution
For classical I came up with 99%cX with x = mass
For special I came up with 70.2%cX with x = mass

What did you get for gamma?
