As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...
A box with mass m = 1.2kg on an inclined frictionless surface is released from rest from a height h = 1.75 m. After reaching the bottom of the incline the box slides with friction (uk = 0.25) along a horizontal surface until coming to a rest after a distance d. 1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names. 2. Draw a free body diagram for...
A 0.40 kg block slides along a small track with elevated ends and a flat central part. The flat part has a length L = 1.46 m . The curved portions of the track are frictionless, but for the flat part the coefficient of kinetic friction is 0.135. The block is released from rest from a height h = 74 cm on the left curved portion of the track. Calculate the maximum height reached by the block on the right...
At a height h = 2.0 m on top a frictionless slope, a block with mass m = 2.5 Kg is given an initial velocity v_i = 5.0 m/s before it slides down towards the rough horizontal surface below. If this horizontal surface has a coefficient of kinetic friction mu_k = 0.4, then: what is the blocks speed after traveling 4.0 m on the rough surface? After coming to a stop how much the internal energy of the whole system...
3m Susand a) A block with a mass of 10.0 kg is AS released from rest at the top of an 1 00.kg inclined track (0 = 30°), at point A, 3.0m above the horizontal (see the figure). The track A to B has a coefficient of kinetic friction of 0.10. The horizontal portion of the track, B to C, is 4.Om long - 4m and is frictionless. At point C, where the horizontal track ends, the block touches the...
3.0 - 6.00 m ASSO 13.0-kg block is released from point A with initial speed of -2.0 m/s ( block is given a push up or down the ramp). The track is frictionless except for the portion between points B and C which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2,000 N/m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. Determine the...
If the coefficient of kinetic friction of a track is 0.1, what
height must an object be released to travel around a loop of radius
R where the distance along the track from release point to the
beginning of the loop is L? The angle the track makes with ground
is
. (The coefficient of kinetic friction of the loop track is
0.)
A roller coaster car of mass 800 kg when released from rest at
point A (height h above the ground) slides along the track and
inside the loop of radius 16.0 m. The car never loses contact with
the track.
A) Draw below a free body diagram for the car the car at the top
of the loop.

what is the speed of the car...
A 16.0 kg block is released from point A in Figure P8.57. 3.60 m -5.50 m The track is frictionless except for the portion between B and C, which has a length of 5.50 m. The block travels down the track, hits a spring of force constant k = 1950 N/m, and compresses the spring 0.340 m from its equilibrium position before coming to rest momentarily. Determine the coefficient of kinetic friction between the block and the rough surface between...
