Going Beyond

 

The following is a common physics problem.

 

A railway car is moving east at 6.25 m/s and collides with another stationary car with a mass of 9.64 x 104 kg. The two freight cars join together at impact and the resulting velocity is 2.89 m/s. What is the mass of the railway car that was originally in motion?

 

Use the formula where

 

V is the combined velocity of both objects after collision

m is the mass of the object in motion

v is the velocity of the object in motion

M is the mass of the stationery object

 

Since you need to solve for m, manipulate the formula. You use similar strategies of solving rational equations to help manipulate the formula for another variable.

 

Manipulate the formula so you isolate m.
