A worker releases boxes at the bottom of a ramp. From the bottom of the ramp the boxes slide 10 m across the floor to a barrier wall. If the ramp is at an elevation angle 0f 20 degrees, how long must the ramp be if the boxes are to reach the wall 2.0s after leaving the ramp? Ignore Friction.

Suppose the hockey puck in the problem above is placed on a different ramp that is not frictionless, but instead has coefficients of static and kinetic friction equal to 0.80 and 0.76, respectively. (a) At what angle would this ramp have to be placed in order for the puck to begin to slide down the ramp? (b) What would be the acceleration of the puck as it slides down this ramp set at the angle calculated in (a) ? (c)...

oblem 2: A 5-kg box slides down a ramp. The ramp is l m in length and inclined at an angle of 30° as shown. The box starts from rest at the top. The surface friction coefficient is 0.25 1. Use energy methods to determine the speed of the box at the bottom of the ramp 2. How far does the box slide before stopping on the horizontal floor if it continues to experience the same friction coefficient. 1.00 m...

A box is sitting on a 2 m long board at one end. A worker picks up the board at the end with the box so it makes an angle with the ground of 35o. The coefficient of static friction between the box and the board is 0.5 and the coefficient of kinetic friction is 0.3 . A) Will the box slide down the ramp when it is at 35o? Prove it! B) How long will it take the box...

A 9.00-kg block of ice, released from rest at the top of a 1.44-m-long frictionless ramp, slides downhill, reaching a speed of 2.88 m/s at the bottom. the angle between the ramp and the horizontal is 17.1 degrees. What would be the speed of the ice at the bottom if the motion were opposed by a constant friction force of 10.8 N parallel to the surface of the ramp? v=?

20) A cart rolls with negligible friction on a ramp that is inclined at an 17 degree angle above level ground. It is released from rest and reaches the bottom of the ramp in 4 seconds. How far did it travel along the ramp? a) What was the vertical height from which the cart was released? b) At the bottom of the first ramp, the cart smoothly rolls onto a second ramp without losing any significant amount of speed. The...

Two packages at UPS start sliding down the 20∘ ramp. Package A has a mass of 3.00 kg and a coefficient of kinetic friction of 0.220. Package B has a mass of 8.50 kg and a coefficient of kinetic friction of 0.170. Package A and B are touching and package A is closest to the bottom of the ramp. Package B pushes package A down the ramp. The distance from package A to the bottom of the ramp is 2...

1. A solid is rolling without slipping down an incline. At the bottom of the incline there is a ramp that creates a "quarter-pipe". A quarter pipe is one quarter of a circle, when viewed from the side. The sphere is released from rest, 4 meters above the bottom of the incline. The sphere rolls without slipping down the incline and back up the quarter-pipe. Thesphere leaves trhe quarter-pipe 30 cm above the bottom of the incline and is launched...
