A 74.2-kg climber is scaling the vertical wall of a mountain. His safety rope is made of a material that, when stretched, behaves like a spring with a spring constant of 1.62 x 103 N/m. He accidentally slips and falls freely for 0.959 m before the rope runs out of slack. How ...

A plane flying a straight course observes a mountain at a bearing of 32.6° to the right of its course. At that time the plane is 6 km from the mountain. A short time later, the bearing to the mountain becomes 42.6°. How far is the plane from the mountain when the second ...

Help, the last equation given to me on previous question was incorrect and I took a 0 % on my assignment !!! A mountain-climber friend with a mass of 82 kg ponders the idea of attaching a helium-filled balloon to himself to effectively reduce his weight by 25% when he climbs...

A small first aid kit is dropped by a rock climber who is descending steadily at 1.3 m/s. After 2.5 s, what is the velocity of the first-aid kit, and how far is the kit below the climber? This problem seems like it should be easy, but I'm not sure which equation to use. I'd ...

A 300kg motorboat is turned off as it approaches a dock and it coasts in toward the dock at .5 m/s. Isaac, whose mass is 62kg, jumps off the front of the boat with a speed of 3m/s relative to the boat. what is the velocity of the boat after Isaac jumps?
