An 8 kg mass is dropped from an 88m tall frictionless ramp. It then collides with a second stationary mass. They stick together and travel across a rough patch with a coefficient of friction of 0.8 for a length of 8m. The masses then fall off a 10m tall cliff where they hit the floor.
How far from the base of the cliff did the two masses travel before hitting the ground?
How fast were they moving right before hitting the ground?(Think vectors)
