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 block with mass M rests on a frictionless surface and is connected to a horizontal spring of force constant k. The other end of the spring is attached to a wall. A second block with mass m rests on top of the first block. The coefficient of static friction between the a blocks is μs. a) Find the maximum amplitude of oscillation such that the top block will not slip on the bottom block. b) Suppose the coefficient of...

A 2kg block and an 8kg block are connected by a relaxed horizontal spring with spring-constant 300N/m. You pull the 8kg block with some constant horizontal force. There is a coefficient of kinetic friction between the blocks and the floor of μk = 0.3. After a time, the spring is stretched a certain constant amount, and the system moves with constant velocity. (a) Draw free-body diagrams for both blocks. (b) What pulling force did you apply? (c) How much is...

A block of mass m = 3.5 kg is attached to a spring with spring constant k = 520 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 21° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk = 0.16. In the initial position, where the spring is compressed by a distance of d = 0.14 m, the mass is at...
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...
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. How large would the coefficient of...

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...

3, A block of mass m = 2.00 kg is attached to a spring of force constant k = 520 N/m as shown in the figure low. The block is pulled to a position ax, -5.15 em to the right of equilibrium and released from rest. x=0 x=x o Find the sped he lodk has as it passes through equililbrium if the horizontal surface is frctionless (b) Find the speed the block has as it passes through equilibrium (for the...

A block of mass “m” sits on a (bigger) block of mass “4m” that is on a frictionless table. The coefficients of friction between the two blocks are μs (static) and μk (kinetic). Assume that a horizontal force “F” is applied to the block on top (i.e. the smaller block with mass “m”). The force “F” is variable. The figure below is representative of this scenario. (You may use m = 10 kg, μs = 0.8, μk = 0.6, and...
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m.
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 25° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk=0.18. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest...
