PHYSICS HOMEWORK # 26 NEWTON'S LAWS FIRST LAW & FRICTION 24. Two masses are sitting on a horizontal surface as shown to the right. The coefficient of sliding friction between these two masses and the horizontal surface is m-0.520. A string is attached to the end of mas m,8.00 kg. This string is then looped arounda pulley and is finally attached to the left vertical surface. The pulley is attached to mass m 12.0 kg as shown and then a...
A box of mass ?=22.5 kg is pulled up a ramp that is inclined at an angle ?=17.0∘angle with respect to the horizontal. The coefficient of kinetic friction between the box and the ramp is ?k=0.305 , and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of ?=2.49 m/s2, calculate the tension ?T in the rope. Use ?=9.81 m/s2 for the acceleration due to gravity. FT=_____N
A 5 kg box is sitting on a table; the coefficient of kinetic friction between the box and the table is 0.6. Two people throw things at it: a lump of clay and a rubber ball. Both objects have a mass of 500 g and strike the box at a speed of 4 m/s. The lump of clay collides inelastically (sticking to the box), while the ball bounces back at a speed of 2 m/s. (a) Without doing any mathematics,...

Two masses are being pulled up a 30.0 degree incline by a force F parallel to the incline. The acceleration down the incline is 1.00 m/s2 and the velocity is up the incline. The force is applied to a 200 kg mass, and a string connects the 200 kg mass to a 150 kg mass. The coefficient of kinetic friction is 0.200. What is the tension in the string? answer: 840 N
A heavy sled is being pulled by two people. The coefficient of static friction between the sled and the ground is μ s = 0.627 , and the kinetic friction coefficient is μ k = 0.459 .

A mass m = 17 kg is pulled along a horizontal floor with NO friction for a distance d =5.8 m. Then the mass is pulled up an incline that makes an angle 0 = 35º with the horizontal and has a coefficient of kinetic friction uk = 0.38. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of 0 = 35° (thus on the incline it is parallel...
