Consider the figure below, which has two objects of mass mi 3 kg connected by a taut rope. m2 Fp m2 Frictionless Finger Ms, Mk = The ramp is at an angle of 0 40° and has the peculiar property that it is frictionless along the tilted surface, but not along its vertical surface. (a) Ignore Fp for this part. What are the magnitude and direction of the acceleration experienced by the two objects? What is the magnitude of the tension force from the rope? (b) As the objects are moving, you apply a force on object 2 (using a frictionless finger) with magnitude Fp 50 N directly leftward (as seen in the figure). Upon doing this, you observe that the objects now move with constant speed. What is ? m₁ Frictionless 5 kg and

The coefficient of static friction is 0.667 between the two blocks shown. The coefficient of kinetic friction between the lower block and the floor is 0.138. Force F causes both blocks to cross a distance of 7.16m, starting from rest. What is the least amount of time in which the motion can be completed without the top block sliding on the lower block, if the mass of the lower block is 1.22kg and the mass of the upper block is 2.10kg?

A 60 kg block slides along the top of a 100 kg block. The lighter block has an acceleration of 3.8 m/s2 when a horizontal force F= 390 N is applied. Assuming there is no friction between the bottom 100 kg block and the horizontal frictionless surface but there is friction between the blocks. Find the acceleration of the 100 kg block during the time the 60 kg block remains in contact.
