A 3.00-kg block is placed at the top of a track consisting of two frictionless quarter circles of radius R equal to 1.98 m connected by a 7.00-m-long, straight, horizontal surface (see the figure below). The coefficient of kinetic friction between the block and the horizontal surface is μk equal to 0.100. The block is released from rest. 1) Find where the block stops, as measured from the left end of the horizontal surface, marked x = 0 on the figure. (Express your answer to three significant figures.)

A block of mass m = 1.0 kg is placed at rest at a distance 8.15 m (measured along the slope) from the horizontal plane on an incline whose surface makes θ=25o to the horizontal as shown in Figure 2. The coefficient of kinetic friction between the surface where the block is placed and the block is μk = 0.19. After the block starts descending on the slope, find the block’s speed at the time when it reaches the bottom...
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
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 track consists of a frictionless arc XY, which is a
quarter-circle of radius R, and a rough horizontal section YZ, as
shown above.
In trial 1, Block A of mass M is released from rest at point
X, slides down the curved section of the track, and collides
instantaneously and inelastically with block B, with mass M, at
point Y. The two blocks move together to the right, sliding past
point P, which is a distance L from point...

Consider the track shown in the figure above. The section AB
is one quadrant of a circle of radius r and is frictionless. B to C
is a horizontal span of length L with a coefficient of kinetic
friction μk. The section CD under the spring is frictionless. A
block of mass m is released from rest at A. After sliding on the
track, it is observed to compress the spring by a distance d.

An air-track glider of mass 0.100 kg is attached to the end of a horizontal air track by a spring with force constant 20.0 N/m. Initially the spring is unstreched and the glider is moving at 1.50 m/s to the right. With the air track turned off, the coefficient of kinetic friction is μk=0.47. It can be shown that with the air track turned off, the glider travels 8.6 cm before it stops instantaneously. If the coefficient of static friction...

Question 7 A 0.73 kg block is placed on a horizontal surface with a coefficient of kinetic friction of 0.122. The block is pressed against a spring that has a spring constant of 683 N/m until it has compressed the spring by 13.7 cm. When the block is allowed to move freely, the spring pushes the block 10 cm along the horizontal surface at which point it encounters an upward slope with an angle of 29.0°. This slope has the...
