2. A block of mass of 12.0 kg is sitting on a frictionless surface. If the block is initially at rest, and a force of 5.0 N parallel to the surface is applied for 13.0 seconds, what is the final speed of the block?
A horizontal constant force of 5.0 is applied ( in a direction that is away from the incline) to a 2.5 kg block that is initially at rest on a frictionless inclined plane (theta = 30 degree) surface. (a) Draw a free body diagram of the block. (b)Using Newton's Second Law find the acceleration of the block. (c) Find the normal force.
A box of mass 19.0 kgkg sits at rest on a horizontal surface. The coefficient of kinetic friction between the surface and the box is 0.300. The box is initially at rest, and then a constant force of magnitude FF and direction 33.0 ∘∘ below the horizontal is applied to the box; the box slides along the surface.a) What is FF if the box has a speed of 6.00 m/sm/s after traveling a distance of 8.00 mm?b) What is the coefficient of kinetic friction that one block exerts on the other?Express your answers with the appropriate units.
A 4.5 kg box slides down a 4.2-m -high frictionless hill, starting from rest, across a 2.2-m -wide horizontal surface, then hits a horizontal spring with spring constant 550 N/m . The other end of the spring is anchored against a wall. The ground under the spring is frictionless, but the 2.2-m-long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.22. Part C How far is the spring compressed? Express your answer...
