Explanation The Figure of pushing down the shoulder of girl by Charlie is shown below. Figure (1) From Figure (1), when Charlie pushes the shoulder of his daughter in forward direction to sled then the normal force and frictional force will be large which obstruct the motion of the slider. Hence, the sled is harder to move in forward direction. The Figure of the pulling up on rope is shown below. Figure (2) From Figure (2), when pulling with the rope there is a component of the applied force that is upward...

3.63 • Leaping the River II. A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at 53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. Ignore air resistance. (a) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank? (b) If his speed was only half the value found in part (a), where did he land? Figure P3.63 53.0° 100 m 40.0 m→ 15.0 m

Please solve and answer the question correctly please. Thank you!!

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 5.00 s after it was thrown. What is the speed of the rock just before it reaches the water 25.0 m below the point where the rock left your hand? Ignore air resistance.
