The 1.0 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is μk = 0.43.

What is the tension in the rope holding the 1.0 kg block to the wall?

What is the acceleration of the 2.0 kg block?

An 85.4-kg climber is scaling the vertical wall of a mountain. His safety rope is made of nylon that, when stretched, behaves like a spring with a spring constant of 1.19 103 N/m. He accidentally slips and falls freely for 0.815 m before the rope runs out of slack. How much is the rope stretched when it breaks his fall and momentarily brings him to rest?

Block A in the figure below has mass 1.30 kg , and block B has mass 2.85 kg . The blocks are forced together, compressing a spring S between them; then the system is released from rest on a level, frictionless surface. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has expanded. Block B acquires a speed of 1.20 m/s . Part A What is the final speed of...

A rope is tied to a tree limb and is used by a swimmer to swing into the water. The person starts from rest with the rope held in the horizontal position, as shown in the figure on the power point file attached, swings downward and then let go of the rope. His initial height is h0 = 415 m and final height is hf = 105 m. If the force due to air resistance is neglected, (30%) What is...

A block having a mass of 10.0 kg is pressed against the wall by a hand exerting a force F inclined at an angle θ of 52° to the wall as shown below. The coefficient of static friction µstat between the block and the wall is 0.20. We shall investigate the question of how large the force F must be to keep the block from sliding along the wall. There is more physics here than initially meets the eye. Think...

A 15.0 kg block is released from rest at point A in the figure below. 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 2,300 N/m, and compresses the spring 0.200 m from its equilibrium position before coming to rest momentarily. Determine the coefficient of kinetic friction between the block and the rough surface between points B...

the figure, block 2 of mass 2.20 kg oscillates on the end of a spring in SHM with a period of 18.00 ms. The position of the block is given by x = (0.600 cm) cos(ωt + π/2). Block 1 of mass 4.40 kg slides toward block 2 with a velocity of magnitude 7.80 m/s, directed along the spring's length. The two blocks undergo a completely inelastic collision at time t = 4.50 ms. (The duration of the collision is...
