A cart can roll on a horizontal track. A force of I IN is applied on the cart. The graph below shows the velocity of the cart as a function of time.

10- Velocity (m/s) 15- - 00 20 Time (s)->> 40 60

5. If we assume the friction is negligible, what is the mass of the cart, in kg?

6. What would be the mass of the cart (in kg), if we did have a frictional force of N

10- Velocity (m/s) 15- - 00 20 Time (s)->> 40 60
