A block is projected up a frictionless inclined plane with initial speed v1 = 3.45 m/s. The angle of incline is 𝜃 = 31.7°.(a) How far up the plane does it go? m(b) How long does it take to get there? s(c) What is its speed when it gets back to the bottom? m/sSection 6.6 Applying Newton's Laws

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.

A 6.6 kg box slides down an inclined plane that makes an angle of 40° with the horizontal.If the coefficient of kinetic friction is 0.2, at what rate does the box accelerate down the slope?Express your answer in m/s2, to at least one digit after the decimal point.

A person pushes a block of mass M = 6.0 kg with a constant speed of 5.0 m/s straight up along a flat surface inclined 30.0° above the horizontal. The coefficient of kinetic friction between the block and the surface is μ = 0.40. What is the net force acting on the block?

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.
