A frictionless plane is 10.0 m long and inclined at 42.0°. A sled starts at the bottom with an initial speed of 5.70 m/s up the incline. When the sled reaches the point at which it momentarily stops, a second sled is released from the top of the incline with an initial speed vi. Both sleds reach the bottom of the incline at the same moment.    (a) Determine the distance that the first sled traveled up the incline.   (b) Determine the initial speed of the second sled.

The figure below shows a motorcycle leaving the end of a ramp with a speed of 39.6 m/s and following the curved path shown. At the peak of the path, a maximum height h above the top of the ramp, the motorcycle's speed is 37.7 m/s. What is the maximum height h? Ignore friction and air resistance. (Enter your answer in m.)

A 1.5-kg box is released from rest on a frictionless surface that is sloped at θ = 35◦ above the horizontal.After sliding 1.0 m down the slope, the box transitions smoothly to a rough, horizontal surface, slides forsome distance, and then comes to a stop. If the coefficient of kinetic friction between the box and thehorizontal surface is 0.12, how far along the horizontal surface does the box travel?

A toy car has a friction coefficient of 0.03. On a 30 degree incline starting from rest, what distance will the toy car have covered after 5 seconds?

A 2kg block slides down a frictionless plane having an inclination of 13.9 degrees. The block starts from rest at the top and the length of the incline is 2.20m. Find the acceleration of the block and it's final velocity when it reaches the bottom.

A 1 kg Box slides down an inclined plane. It has an incline of 1.25664 radians and coefficient of kinetic friction of 0.44. What is the final speed of the Box if it started at rest and the change in height is 4 m? V =

A 2.1 x 10-kg car starts from rest at the top of a 5.8-m-long driveway that is inclined at 15° with the horizontal. If an average friction force of 4.0 x 103N impedes the motion, find the speed of the car at the bottom of the driveway. Enter a number. differs from the correct answer by more than 10%.

You are driving your car on a straight road with a coefficient of friction between the tires and the road of 0.55. A large piece of debris falls in front of your view and you immediate slam on the brakes, leaving a skid mark of 30.5 m (100-feet) long before coming to a stop. A policeman sees your car stopped on the road, looks at the skid mark, and gives you a ticket for traveling over the 13.4 m/s (30 mph) speedlimit. Draw the FBD of the car with complete details.

Your answer is partially correct. In the figure a block slides along a path that is without friction until the block reaches the section of length L = 0.66 m, which begins at height h = 1.1 m, on a ramp of angle 0 = 32°. In that section the coefficient of kinetic friction is 0.410. The block passes through point A with a speed of 8.4 m/s. If the block can reach point B (where the friction ends), what is its speed there, and if it cannot, what is its greatest height above A? Number i 8 6.46 Unit m/s

A block is placed on a frictionless ramp at a height h; of 14.5 m above the ground. Starting from rest, the block slides down the ramp. At the bottom of the ramp, the block slides onto a frictionless horizontal track without slowing down. At the end of the horizontal track, the block slides smoothly onto a second frictionless ramp. 01 = 43.3° 02 = 19.5° How far along the second ramp does the block travel before coming to a momentary stop, as measured along the incline of the ramp? distance traveled along second ramp: m After the block comes to a complete stop on the second ramp, it will then begin moving back down the second ramp. What is the speed of the block when it is 9.25 m, vertically, above the ground? speed of the block: m/s
