... ANSWER: (a) 12kJ;(b) -11 kJ; (.) 1.1 kJ; (d) 5.4 m/s 6. A block of ice slides down a frictionless ramp at angle = 50o while an ice worker pulls on the block (via a rope) with a force F, that has a magnitude of 50 N and is directed up the ramp. As the block slides through distance d = 0.50 m along ...

Forces and Newton`s Laws
... Summarize the relationship between a moving object’s mass, its inertia, and the forces acting on it. Accept all reasonable responses. The greater the object’s mass, the more inertia it has, and the larger the net force needed to change the object’s velocity. A moving object will tend to keep moving ...
