Question

Cart Mass =200kg
String compressed by = 5m
Initial velocity =25 m/s

Find the potential energy stored by the spring while it was compressed.

Answer 1

So do you know the formula for PE?

Answer 2

m*g*h

Answer 3

If the Floor is frictionless then the Kinetic Energy of the Cart will be Converted to P.E of the Spring

\[K.E=\frac{ 1 }{ 2 }mv^2\]

\[\frac{ 200*25 }{ 2 } = 2500J\]

Answer 4

So that would be the potential energy?
