A 1 kg block, starting from rest, slides down a 22 degree inclined plane that is .55m tall. At the bottom, the 1 kg block collides with a 3 kg block. The two blocks stick together and slide .52 m on a friction less horizontal surface for .52 sec. What is the speed of the 1kg block before it collides with the 3 kg block? What is the acceleration of the 1kg block as it travels down the inclined plane? What is the coefficient of friction between the 1kg block and the inclined plane, mk?

A block slides down an inclined plane, starting from rest and being pushed with a constant acceleration of 5.25 m/s2 over a distance of 18.0 cm. It then decelerates at a constant rate of 1.10 m/s2 (because of friction), until it again comes to rest. Find the total time the block is in motion.

A block m1= 0.5kg slides on a plane inclined at 300 to the horizontal. It is attached to a string which runs over a pulley and has a mass m2=0.2kg hanging at the other end. The coefficients of friction between the block m1 and the plane are: μs = 0.4 and μk = 0.3 . Assume that at t=0s, the block m1 is moving down the incline. Refer to this moment and: a) Draw FBD for both blocks. b) Write...
