(a)For what value of m2 (in kg) will the system be in equilibrium?m2 = kg(b)If the block has to slide down the incline with an acceleration of 0.7 m/s2, what should be the value of m2 (in kg)?m2 = kg

Block A, with mass 15 kg, sits on an incline of 0.53 radians above the horizontal. An attached (massless) string passes through a massless, frictionless pulley at the top of the incline as shown:The coefficient of kinetic friction between block A and the incline is given as 0.32. When the system is released from rest, block B accelerates downward at 1.1 m/s2. What is the mass of block B?Express your answer in kg, to at least one digit after the decimal point.

m The object of mass m = 3 kg is at the bottom of the incline, which is at the angle e = 55° with respect to horizontal. The object has initial speed of vo = 5 m/s and begins slide up the incline. There is a friction between the object and the incline. The coefficient of kinetic friction is uk = 0.25. The object moves up the incline and eventually stops under the influence of friction and its own weight. Find: (a) how high up the incline (in m, relative to its original position) the object slides before stopping (careful here - your answer is the height, i.e. the vertical distance between object's final position and the ground); (b) work in J) done by the kinetic friction when the object moves up the incline (careful with the sign); (c) work in J) done by the normal force when the object moves up the incline; (d) work in J) done by the gravity when the object moves up the incline (careful with the sign); (e) when the object reaches the highest point on the incline it begins to slide back down, find object's speed (in m/s) at the bottom of the incline.

Two blocks A (mass = 10 kg) and B are connected together by a string and placed on a smooth fixed right angled incline. The pulley and string are massless. The system is at rest. Then which of the following options is/are correct?

`A 40 kg slab rests on a frictionless floor. A 10 kg block rests on top of the slab. The static coefficient of friction between the block and the slab is 0.60 while the kinetic coefficient is 0.40. The 10 kg block is acted upon by a horizontal force of 100 N. If g = 9.8 m/s2 the resulting acceleration of the slab will be  A.0.98 m/s2B.1.47 m/s2  C.1.52 m/s2D.6.1 m/s2
