A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of u. The block is subject to the normal force, the friction force, the force of gravity, and a force from a rope of magnitude T which pulls up and to the right at an angle of with the horizontal. The box was initially travelling to the right at speed v = 2.7 If M =9.0kg, u=0.17,...

A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg.
A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right.Part (a) Solve numerically for the magnitude of the normal force, FN in newtons, that acts on the block if θ = 30°. Part (b) Solve...

An object of mass m = 1.70 kg is travelling on a horizontal surface. The coefficient of kinetic friction between the object and the surface is muk = 0.200. The object has speed v = 1 .35 m/s when it reaches x = 0 and encounters a spring. The object compresses the spring a distance d/2, stops instantaneously, and then travels back to x = 0 where it stops completely. Eventually you will be asked to find the spring constant,...

. A 2.00kg block is moved from point A (at rest) a distance of 2.00 m to point B under the action of a variable force F(x) 10x + 6x2. Once in point B it is moving down 1.00 m through an 60.00 inclined frictionless surface until hit a spring (point C) as shown in figure.
