Q. Runner A is initially 6.0 km west of a flagpole and is running with a constant velocity of 5.5 km/h due east. Runner B is initially 7.0 km east of the flagpole and is running with a constant velocity of 6.5 km/h due west. How far are the runners from the flagpole when their paths cross?
Q. The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 3.18 m/s. If non-conservative forces, such as kinetic friction and air resistance, are negligible, what would be the height h of the highest point reached by the skateboarder on the right side of the ramp?
A 100 kg rocket moving radially outward from Earth has a speed of 4 km/s as its engine shuts off 200 km above Earth's surface.
A 240 , 50.0-cm-diameter turntable rotates on frictionless bearings at 57 . A 22 block sits at the center of the turntable. A compressed spring shoots the block radically outward along a frictionless groove in surface of the turntable. What is turn..
