A m= 500. kg Initial Velocity at point A = 1.5m/s

A 10 kg block slides down a frictionless incline as shown. Find its speed when it reaches the bottom.

There is a slider with a circular shape shown a radius A Ol to below with with a boy m. of 2oka starts sliding the top of the slider at point A. His speed at mass down from A is zero, Assume point the re FoN and Hthe olider surface. Determine Ca) the boy's speed at the of the glider at point B, and (b) the value of the force is no friction between the bottom that the b0y exerts on the slider at point B. A r= 1 0m r=lom B

A 1kg ball swings in a vertical circle at the end of a 1m-long string. R (a) If the ball can just (barely) make it to the top of the circle, what is the tension force when it reaches the top? Answer (b) Under the condition in (a), what is the speed of the ball when it is at the top? Answer: m/s (c) What is the required speed of the ball at the bottom of the circle so that it can just make it to the top as described in (a)?

How long will it take a 3750-W motor to lift a 425-kg piano to a sixth-story window 18.0 m above?

A 169 N weight elevator carries 20 passengers, which have an average weight of 710 N, a distance of 3.5 m. To get to the second floor, use a time of 18 seconds. What is the minimum power that the motor makes??

A small block of mass m= 2 kg slides on a frictionless track as shown in the figure below. Find (a)  The speed of the block at B, if it starts at rest from point A? (b) What is the force of the track on the block at B? (Given, the radius of the loop R = 10.0 m)

A simple lever is used to lift a heavy load. When a 62-N force pushes one end of the lever down 1.3 m , the load rises 0.22 m .    What is the gain in potential energy of the load?

A 67.5-kg skier encounters a dip in the snow's surface that has a circular cross section with a radius of curvature of 12.0 m, as shown below. The snow is so slippery it can be considered to be frictionless. If the skier's speed a point A is 9.64 m/s, what is the skier's speed at point B?
