Problem-
Use the value obtained for the cart's coefficient of rolling friction and determine how far it will travel if given an initial speed of 20 cm/s across a flat, level surface?

The cofficient of rolling friction is -.0122
What formula do we have to use? do i just mutiply -.0122 x 20?

1. What will be the acceleration (or deceleration?) of the mass?

2. Can you write an equation involving the velocity as a function of the distance covered by the mass (cart)?
