Each person pushed a 5.7kg mat from one line to the other (5m). There are times recorded for each person who pushed the mat. Calculate the work to push the mat, the power to push the mat and the coefficient of friction between the mat and the floor.

Times:

1.59s

1.72s

1.94s

49) A 2.0-kg box is pushed from rest by a person exerting a constant force of 50 N. The person exerts this force over a distance of 3.0 m before releasing the box and letting it slide to a stop. The coefficient of kinetic friction between the box and the floor is 0.15. (a) Draw a motion diagram showing the motion of the box from the moment the person begins pushing to the moment the box stops moving. (b) Represent...

1) You wish to accelerate a small merry-go-round from rest to a rotational speed of one-fourth of a revolution per second by pushing tangentially on it. Assume the merry-go-round is a disk with a mass of 300 kg and a radius of 2.00 m . Ignoring friction, how hard do you have to push tangentially to accomplish this in 6.00 s ? (Use energy methods and assume a constant push on your part.) F=? 2) A person opens a door...

A person pushes on a 74 kg refrigerator by a horizontal force of 215 N. (Assume the push is in the +x-direction.) #1) If the coefficient of static friction is 0.65, what are the magnitude (in N) and the direction (in degrees counterclockwise from the +x-axis) of the force of the static friction? Does the person move the refrigerator? #2) What is the magnitude (in N) of the largest push that the person can apply to the refrigerator just before...

Question 1 During a rugby game two players are running toward each other. One has a mass of 83.9 kg and the other has a mass of 59.9 kg. The player who has the bigger mass is running at 1.90 m/s and the other is running at 4.70 m/s. They hit each other, fall to the ground and slide while attached to each other. If the coefficient of kinetic friction between the players and the ground is 0.300, how far...

5 masses are arranged in ascending order of mass from left to right, each mass is suspended between 2 springs vertically from a fixed wooden frame. By pushing up and down on a plastic lever at the bottom of the frame, the frame can be vertically shaken. If pushing down on the lever 18 times in 10 second intervals causes the middle mass to swing vertically with a large amplitude, how frequently would you have to push down on the...

Suppose 200 people are lined up side-by-side, each one holding a fair coin. Each person flips their coin 64 times; every time it lands heads they step 1 meter forward, each time it lands tails they step 1 meter backward. Use a normal approximation to answer the following question: after everyone finishes their 64 steps, approximately how many people will be standing between 4 and 8 meters behind the starting line? (Round your answer to three decimal places. Example: if...

Two loudspeakers are in phase and both producing 458-Hz sound waves 3 meters from each other. A person initially stands 1.6 meters in front      of one of the speakers. The person then walks directly away from this speaker. How far will the person have walked when they hear the combined sounds from the two speakers reach a minimum in loudness for the third time? The power output of each speaker is 2.40 mW. What is the sound intensity level...

Starting from rest, two skaters "push off" against each other on smooth level ice, where friction is negligible. One is a woman and one is a man. The woman moves away with a velocity of +2.7 m/s relative to the ice. The mass of the woman is 50 kg, and the mass of the man is 81 kg. Assuming that the speed of light is 4.4 m/s, so that the relativistic momentum must be used, find the recoil velocity of...
