You are riding in an elevator on the way to the 18th floor of your dormitory. The elevator is accelerating upward with a = 1.90 m/s2. Beside you is the box containing your new computer; the box and its contents have a total mass of 36.0 kg. While the elevator is accelerating upward, you push horizontally on the box to slide it at constant speed toward the elevator door. If the coefficient of kinetic friction between the box and the elevator floor is mk = 0.32, what magnitude of force must you apply?

A hot air balloon begins to rise from rest. The lift on the balloon due to the buoyant force is 5000 N. In order to minimize the time until the passenger is reunited with their cell phone, what should the horizontal component of the passenger’s velocity be so that they land directly on their phone which is initially 3 m away in the horizontal direction?
You are given the job of moving a refrigerator with a mass of 1.8 x 102 kg across a horizontal floor. The coefficient of static friction between the refrigerator and the floor is 0.45. Calculate the magnitude of the minimum force that is required just to set the refrigerator into motion.
A student takes the elevator up to the fourth floor to see her favorite physics instructor. She stands on the floor of the elevator, which is horizontal. Both the student and the elevator are solid objects, and they both accelerate upward at 5.35 m/s2. This acceleration only occurs briefly at the beginning of the ride up. Her mass is 88.0 kg. What is the normal force exerted by the floor of the elevator on the student during her brief acceleration? (Assume the direction is upward.)
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 44° angle. You estimate that the mass of the sled, with your friend on it, is 70 kg and that you're pulling with a force of 71 N. Part A What answer will you give? ΠΙ ΑΣΦ Submit Request Answer ?
Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?
Consider two blocks connected . Block A has mass 2.00 kg, and block B has mass 5.00 kg. The table on which B sits is frictionless, the cord connecting the blocks is light and flexible, and the pulley is light and frictionless.

In a movie, a stuntman places himself on the vertical front of a truck as the truck accelerates. The coefficient of static friction between the stuntman and the truck is 0.370. The stuntman is not standing on anything but can “stick” to the front of the truck as long as the truck continues to accelerate. What minimum forward acceleration will keep the stuntman on the front of the truck?
A 92.4 kg person is standing inside an elevator. The person is riding the elevator from the 12th floor down to the 3rd floor (a distance of 30.8 m).
