A magician wants to do the trick in which he pulls a tablecloth from a table, leaving the items on the table behind, unmoved. It turns out that this isn't magic at all, but simple physics. Let's assume that the tablecloth has to be slide horizontally a distance of 50 cm before it has slipped out from underneath a dish that lays on top of it. If the tablecloth's mass is 2 grams and the dish has a mass of...
Somewhat surprisingly, your physics skills land you a position on the competitive shuffleboard team. You release a disk (mass 0.425 kg ) with speed 1.71 m/s, and it eventually stops due to friction. The coefficient of kinetic friction between the disk and the waxed surface is 0.100. What is the work done by friction bringing the disk to a stop? What is the average thermal power emitted by the disk as it stops?
. You are using a rope to pull a sled at a constant velocity across level snow, with coefficient of kinetic friction 0.050 between sled and the snow. The sled is loaded with physics books, giving a total mass of 48 kg. (a) With what force should you pull with the rope horizontal? (b) Repeat for the rope at 30 ̊above horizontal.
You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...

Q12: You pull a box with a mass of 100 kg across a rough surtac using a rope, applying concrete) and the horizontal force. The static friction coeffcient is 1.0 (e.g kinetic friction coefficient is 0.8 (a) (8 pts] Which is the minimum force needed to make the box alternatively, the maximum force that can be applied before it starts start moving (or moving)? (b) 18 pts] if you continue to apply the same force once the...

The box has coefficients of friction of .22 and kinetic friction of .14 with the floor. a. If you are pulling the box with a horizon ou are pulling the box with a horizontal force to the right, what is the force you will need to get it started...
You are a fitness trainer developing an exercise that involves pulling a heavy crate across a rough surface. You attach a rope to a crate of mass M = 45.0 kg and place it on a carpeted track. Using your physics expertise, you have already determined that the coefficient of kinetic friction between the crate and the carpet is μk = 0.430. To test the apparatus, you have one of your employees pull on the rope as hard as she...

..sliding down a grass hill on a piece of cardboard was a fun summer activity! There was a hill near a park in south St. Louis that had an incline of something like 30 degrees. Once I got started on the top of the hill, I could ride for a distance on the order of 50 meters before arrived at the bottom of the hill. At that time, my mass was just a puny...
You promised your younger brother that you would give him a ride on his sled. (Take the positive i direction to be to the right and the positive j direction to be upward.) (a) You first pull him with a force F53.21.0j) N. If the mass of the sled and boy is 59.0 kg and the coefficient of kinetic friction is 0.061, what is the acceleration of the sled? Express your answer in vector form. m/s you decite to push...
I just need help with part C please! I'm struggling! Thank
you.
a) If half of the weight of a flatbed truck is supported by its two
drive wheels, what is the maximum acceleration (in m/s^2) it can
achieve on dry concrete where the coefficient of kinetic friction
is 0.7 and the coefficient of static friction is 1.
The answer is 4.9 m/s^2.
b) Will a metal cabinet lying on the wooden bed if the truck
slip if it accelerates...
