A 40.0-N crate starting at rest slides down a rough 6.00-m-long ramp, inclined at 30.0° with the horizontal. The magnitude of the force of friction between the crate and the ramp is 6.0 N. What is the speed of the crate at the bottom of the incline? O (a) 1.60 m/s O (b) 3.32 m/s O (C) 4.5 m/s O(d) 6.42 m/s O (e) 7.75 m/s

A 02 UBC Engineering A trapeze artist of a mass of M to 01 trick. If the ropes do NO work on the artist, what is the speed just before they let go? What is their normal acceleration? 79kg is attempting a new trick on a rope of l 70° and then rope A is cut. The artist holds on until when 02 = 15° then lets go for the next 15m. They are lifted Neglect size and air resistance

A man does 4,480 J of work in the process of pushing his 2.70 103 kg truck from rest to a speed of v, over a distance of 25.5 m. Neglecting friction between truck and road, determine the following. (a) the speed v (in m/s) m/s (b) the horizontal force exerted on the truck (in N) N

A block slides along a track with an initial velocity vo = 7.0 m/s from one level to a higher level after passing through an intermediate valley. The difference h from the initial position to the elevated track is 0.89 m. The track is frictionless until reaches the top. There (at the top), a frictional force stops the block in a distance d. The coefficient of kinetic friction  between the block and the surface is 0.60. Find the distance d.

A 4.00kg block moves with an initial speed of3.50 km/h downhillover an inclined plane as shown in the figure. The height of the inclined plane is 51.3cm and the friction coefficient between the block and the incline is 0.120. a.How much is the speed of the block at the midpoint of the inclined side. b.How much is the speed of the block at the bottom of the inclined side.

A man does 4,570 J of work in the process of pushing his 2.40  103 kg truck from rest to a speed of v, over a distance of 27.0 m. Neglecting friction between truck and road, determine the following. (a) the speed v (in m/s)  m/s (b) the horizontal force exerted on the truck (in N)  N

10. Block 1 with a mass of 1.0 kg slides down a frictionless ramp with a height of 3.0 m and cllides with block 2 which has a mass of 2.0 kg. The flat surface has friction with a friction coefficient of 0.50. 2 a. Determine the speed of block 1 when it reaches the bottom of the ramp.

A 4.25 kg block is projected at 5.40 m/s up a plane that is inclined at 30.0° with the horizontal. The block slides some distance up the incline, stops turns around and slides back down to the bottom. When it reaches the bottom of the incline again, it is traveling with a speed of 3.80 m/s. If the coefficient of kinetic friction between the block and the plane is 0.500, how far up the incline did the block slide?
