Webb24 nov. 2024 · When a force pushes something that can freely pivot (like a door on its hinges), that thing will turn instead of moving. Now try opening the same door by pushing with one finger near the hinge. This time it's much harder. The shorter the distance between the force and the pivot point, the harder it is for the force to make something turn. WebbA girl on a skateboard (total mass of 40 kg) is moving at a speed of 10 m/s at the bottom of a long ramp. The ramp is inclined at 20° with respect to the horizontal. If she travels 14.2 m upward along the ramp before stopping, what is the net frictional force on her? 41. A baseball of mass 0.25 kg is hit at home plate with a speed of 40 m/s.
