The 1.0 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is μkμk = 0.42. What is the acceleration of the 2.0 kg block

Use g = 10 m/s2 Always answer in standard units (SI units). Unless otherwise instructed.  Answer to 2 decimal places. Unless otherwise instructed.  Consider an object of mass m starting from rest and sliding down a ramp. The ramp makes angle theta = 30 degrees relative to the ground. The coefficient of static friction and the coefficient of kinetic friction between the object and the ramp are both 0.5. The distance S = 1m between the object and the end of the ramp. What is the speed of the object when it reaches the end of the ramp?

A sled is on a horizontal surface and a rope with tension T is pulling on it at an angle e above the horizontal. The sled had mass M and does not move due to the frictional force. In this case the coefficient of friction is ug. In terms of the variables given and g, what is the magnitude of the frictional force in this case? Select one: O a. Tcose O b. H, Mgsin0 Ос. Tsin® O d. H, Mgcose

A crate that has a mass of m = 3.5 kg rests on a horizontal plane. The coefficient of static friction, μs, is 0.25. A horizontal force, F, is applied to the crate, and it is just enough to get the crate to begin moving.a. write an expression for the sum of the forces in the x-direction using that Ff is the static friction force, FN is the normal force and Fg is the weight.b. write an expression for the sum of forces in the y-direction using the same coordinate systemc. calculate the magnitude of F, in newtons, Ff is at its maximum

Santa Claus tries to drag his bag of presents along a horizontal surface by a red rope that is angled at 55 degrees above the horizontal. Santa Claus applies a force due to tension of 4500N along the red rope. This is the minimum force to just start the bag in motion. The coefficient of kinetic friction between the bag and the ground is 0.3 and the coefficient of static friction is 0.5. What is the mass of the bag?

you are driving down the road and are speeding. You apply the brakes on your car until you slow down to 22.4 m/s. A computer plots the force versus time for the vehichle and then measures the area under the curve. The area is -18950 N per s. The total breaking is 5.4 seconds. The combined mass of the car is 1200 kg. How fast were you moving before applying the breaks? What is the average force applied by the road to thr car before breaking?

ou are pushing your friend in his wheelchair. You are both taking his dog, Wrathbone, to the vet. Wrathbone is 5 kg and is sitting in your friend’s lap. You decide to increase the wheelchair’s acceleration to 7 ms2 in order to get up a steep ramp. If your friend has a mass of 46 kg and his wheelchair has a mass of 16 kg. What is the force you are applying?

A student is pulling a crate with a mass of 66.6 kg along a horizontal frictionless floor with a rope that’s inclined at an angle θ = 30.0° above the horizontal as shown. The tension force is measured to be 239 N. What is the magnitude of the normal force on the crate from the floor, in Newtons? Use g = 10.0 m/s2.    Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
