You wish to push a cart across a frictionless surface, so you apply a force of 50 N force for a period of 50.0 seconds. As a result the cart goes from rest to a velocity of 2.3 m/s. What is the
mass? Hint (must find acceleration first.)

Akg a of 55 m at an of 11 ? . if is at 98 km/h,be ?

Which sections of the heating curve illustrate this process?
