QUESTION 5 A mass of 12 kg is placed on a horizontal surface with friction with a coefficient of static friction of 0.81 and coefficient of kinetic friction of 0.44. A force of 13 Newtons is applied in the -y direction and a force of 16 Newtons is also applied in the -y direction. Another force is applied in the +x direction (see sketch). The force applied in the +x direction is increased until it is 1.9 times the force...

A heavy bullet of mass m = 0.1200 kg is fired with an initial velocity v = 400. m/s into a large block of lightweight wood of mass M = 0.500 kg, which is initially at rest on a frictionless surface. This initial situation is depicted on the left side of the picture below. The bullet gets stuck inside of the wood block and both move together thereafter as shown in the picture. a) What is the velocity V of...

A box of mass 11[kg] is being pushed up a frictionless inclined plane by a force of 700[N]. The slope of the plane is 37 degrees. The box is pushed at 37 degrees – so the push is in exactly the same direction as the direction of the plane. Assume that the box was initially at rest. Suggestion: Draw a picture of this situation Draw a free body diagram for the box b. Draw a tilted free body diagram such...

A hanging weight, with a mass of me = 0.350 kg, is attached by a rope to a block with mass m2 = 0.820 kg as shown in the figure below. The rope goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R2 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As...

Imagine a 4.0-kg wood block sliding across a horizontal table surface with a positive velocity and an acceleration of -2.0 m/s. You need to calculate the coefficient of kinetic friction for these two surfaces. 1. Start the same way you always should whenever you have a question involving forces and accelerations. Draw a free-body diagram (arrows for all the forces, arrow for net force, and a coordinate system) for the block. All the forces, vertical as well as horizontal. 2....
