A 0.19 kg hockey puck slides across an icy surface and experiences a small friction force of 0.09 N. If the puck is given an initial velocity of 4m / s how far does it slide before stopping? Your answer should be in units of m but you should only submit the number for your answer.

Mary applies a force of 71 N to push a box with an acceleration of 0.45 m/s2. When she increases the pushing force to 79 N, the box's acceleration changes to 0.63 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?

An object of mass 3.1 kg with a certain initial speed on a horizontal surface comes to rest after traveling a distance of 15.9 m. If the coefficient of kinetic friction between the object and the horizontal surface is 0.27, what is the initial speed of the object? Express your answer in m/s, to at least one digit after the decimal point. plz use q =9.8

A 128 lb person steps into an elevator at the ground floor. The elevator accelerates upward at 5.0 ft/s^2 until reaching a velocity of 24 ft/s. It then holds this velocity until decelerating (a=-5.0 ft/s^2) to a stop at the top floor. What is the normal force on the person in each of the three phases of this trip?

14. A 66.0 kg skier with an initial velocity of 9.30 m/s slides up a slope of 35.0° to a height of 2.50 m above where she started. The coefficient of kinetic friction is 0.0750. a. Find the force due to friction on the hill. b. Find the skier's velocity at the top of the hill. V = ? KE₁ Vi 35° 2.5 m

A 1.2 kg crate slides down a 300 ramp with a height of 2.77. The crate has a speed of 2.90 m/s at the bottom of the ramp. The ramp is 5.8 m long. What is coefficient of kinetic friction?

Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.

What net force is required to make a 15 kg box move at a constant speed of 2.0 m/s.

A person catches a ball with a mass of 145 g dropped from a height of 60.0 m above his glove. His hand stops the ball in 0.0100 s. What is the force exerted by his glove on the ball? Assume the ball slows down with constant acceleration.

A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?
