A student attaches a rope to a 32 kg box, and drags it to the left with constant velocity of 1.97 m/s. The tension in the rope is 207 N at an angle of 35.7° to the ground. How much does the box weigh? Find the x and y components of the applied (tension) force: Fx = N Fy= N. %3D How much friction must be present? How much Normal force must be present?

A warehouse worker applies a force F to accelerate two crates, mã and mp, to the right along a rough floor. Crate mд has a mass of 4m, crate mp has a mass of m. Choose 1 answer: A F Which is the correct relationship between the applied force F acting on mд and the force mд exerts on mB? B D MA mB The force Facting on my is smaller than the force that mA exerts on MB. The force Facting on my is the same as the force that mA exerts on MB. The force Facting on my is larger than the force that mд exerts on MB. The answer depends on the relative size of the friction force on MA and MB.

A robot pushes a 20-kg giftbox on the horizontal surface as part of the moving job for the holiday season, the force is 79 N to the right as shown. The box does not move. The coefficients of friction between the floor and box are μs = 0.75 and μk = 0.40. What is the magnitude (absolute value) of the friction force on the box, in Newtons? Use g = 10 m/s2.

Two workers are sliding 390 kg crate across the floor. One worker pushes forward on the crate with a force of 450 NN while the other pulls in the same direction with a force of 290 NN using a rope connected to the crate. Both forces are horizontal, and the crate slides with a constant speed. What is the crate's coefficient of kinetic friction on the floor?

A 1.0-kg block slides on a rough horizontal surface. A force, P = 9.0 N, is applied to the block at an angle to the horizontal as shown. The magnitude of the block's acceleration along the surface is 3.5 m/s?. What is the magnitude of the force of friction acting on the block? 30° 1.2 N 4.3 N 6.5 N O 15 N 7.2 N 9.0 N

You want to push a 22.0 kg rock up a 42.0° hill. You do so by pushing the rock with a 432.0 N horizontal force. The coefficient of kinetic friction between the rock and the hill is 0.125. What is the acceleration of the rock up the hill? What's the normal force from the hill on the rock?

A box is placed on a rough floor. When you push horizontally against the box with a 40N force, the box just begins to slide. What is the magnitude of the friction force when you push against the box with a 25 N force? O58 N O 15 N O 40 N 98 N O none of the answers O 25 N

You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 263 N in the positive x direction to try and move the 54 kg refrigerator. The coefficient of static friction is 0.59. How much static frictional force does the floor exert on the refrigerator? Give both magnitude (in N) and direction.

The two blocks are sliding down the incline. Block 1 has a mass m1 = 1.2 kg  and the cooefficeint of kinetic friction between the block and the floor is μk1 = 0.21. For block 2, m2 = 4.4 kg  and μk2 = 0.11. What is the tension in the massless string?
