You are pushing a 10 kg table across a level floor with a force of 30 N. You are causing it to accelerate at 0.2 m/s^2. What is the coefficient of friction between the table and the floor?

Consider a wooden ramp angled 30.1 degrees above horizontal. If a 10.2-kg wooden block is given a strong shove up the ramp so that it has an initial velocity of 28.6 m/s, how long (in seconds) will it take the block to reach its maximum height (before it starts sliding down)? The coefficient of kinetic friction between the block and the ramp is 0.410.

You are pulling on a box (that has a 5.9 kg mass) by using a rope, pulling upward with a force of 7.2 N at an angle of 28.1°. If the box is moving across the ground at a constant speed of 11.6 m/s, what is the coefficient of kinetic friction? Your Answer: Answer

A single-celled animal called a paramecium propels itself quite rapidly through water using its hair-like cilia. A certain paramecium experiences a drag force of Fdrag -bu? in water, where the drag coefficient b is approximately 0.330 kg/m. If the paramecium's speed v is 0.000157 m/s, what is the magnitude of the propulsion force that the creature must generate to move at this constant speed? -9 magnitude: 2.684 x10° N

A 1.09 kg block is placed at one end of a wooden plank that is 2.02 m long. The plank is slowly tilted. M (a) The block starts to slide when the angle reaches 16 degrees. What is the coefficient of static friction between the block and the ramp? (b) The coefficient of kinetic friction between the block and the ramp is about 0.20. At what rate will the block accelerate down the plank if it is tilted at 16 μκ degrees?

A 51.9 kg crate is hung from the ceiling by two wires. Each wire makes an angle of 41 degrees with the ceiling. What is the tension (in newtons) in one of the wires?

A 10.0 kg object is pushed across a floor with a horizontal force of 70.0 N. If the coefficient of kinetic friction between the object and the floor is 0.100, what is its acceleration?

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?

A 30-kg box is being pushed along a horizontal surface. The coefficient of static friction between the box and the ground is 0.45, and the coefficient of kinetic friction is 0.35. What horizontal force must be exerted on the box for it to accelerate at 1.2 m/s2?

The coefficient of static friction between block A and a horizontal floor is 0.470, and the coefficient of static friction between block B and the floor is 0.300. The mass of each block is 2.00 kg, and they are connected together by a cord. What is the tension in the cord connecting blocks A and B just before they start to slide?
