You are at the grocery store pushing on a shopping cart. The mass of the cart including all the delicious food you will buy is 22.0 kg. The coefficient of friction between the floor and the wheels of the shopping cart is 0.22. In order to accelerate the cart to 2.20 m/s from rest in 2.20 m, what force must you apply to the cart?

A delivery company has unloaded a 35 kg crate in your driveway. The coefficient of static friction between the crate and the driveway surface is s = 0.70. The coefficient of kinetic friction is k = 0.60. In order to move the crate, you apply a horizontal force of magnitude F by pushing on it. As a result, the crate slides with an acceleration of 5.0 m/s². What is the force F? Express your answer with the appropriate units. F = 380 N Submit VP 5.8.2 Correct Part B Previous Answers John and Dave are having a disagreement about where to place a new refrigerator in their kitchen. As shown in (Figure 1), John is applying a Fj = 230 N force to the right, and Dave is pushing back in the opposite direction with a force FD. The fridge has a mass m = 80 kg. The coefficient of static friction between the fridge and the floor is μ = 0.40, and the kinetic coefficient is k = 0.20. If Dave is pushing harder than John, what is the direction of the friction force? Down Up From John to Dave From Dave to…

A 30 kg object sits on a table. The coefficient of static friction between the object and the table is 0.25. What frictional force must you overcome to make the object move?

It's a snowy day and you're pulling a friend along a level road on a sled. You've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. You've been walking at a steady 1.5 m/s, and the rope pulls up on the sled at a 41° angle. You estimate that the mass of the sled, with your friend on it, is 56 kg and that you're pulling with a force of 88 N.

A heavy crate is suspended from two ropes as it is lowered from a high shelf to the floor at a constant speed. One of the ropes makes an angle of 26.5 degrees with respect to the vertical and has a tension of 653 N, while the other makes an angle of 31.5 with respect to the vertical. What is the crate's mass in kg?

A boy pulls a sled of mass 5.0 kg with a rope that makes a 60 degree angle with respect to the horizontal surface. He pulls on the rope with a force of 10.0 N; and the sled moves with constant velocity. What is the coefficient of friction between the sled and the ice?

A 1.0 N block is pushed against the ceiling by a 3.5 N force at a 60° angle as shown in the figure. The coefficient of static friction between the block and the ceiling is 0.9. If the block is in equilibrium, what is the magnitude of the frictional force acting on the block. 60° 3.50 N O 1.75 N O 2.73 N O 3.63 N 0.9 N

A 1250 kg boat is traveling at 90 km/h when its engine is shut off. The magnitude of the frictional force fk between boat and water is proportional to the speed v of the boat. Thus, fk = 80v, where v is in meters per second and fk (the magnitude of the frictional force) is in newtons. Find the time required for the boat to slow down to 45 km/h.

Mary applies a force of 78 N to push a box with an acceleration of 0.49 m/s2. When she increases the pushing force to 86 N, the box's acceleration changes to 0.73 m/s2. There is a constant friction force present between the floor and the box. (a) What is the mass of the box in kilograms?  kg (b) What is the coefficient of kinetic friction between the floor and the box?

A crate of mass 33.9 kg rests on a level surface, with a coefficient of kinetic friction 0.142. You push on the crate with an applied force of 378 N. What is the magnitude of the crate s acceleration as it slides?
