Question about #4
Prove that tan theta is equal to mu_k when the block slides down the incline with a constant speed. (Use symbols, not numbers.) If theta is the maximum angle of incline just before the block moves, what is mu_s, in terms of theta? Suppose that the block were made to move up the inclined plane with a uniform speed by suspending masses on a string over the pulley. Derive an equation for the coefficient of kinetic friction...

A mass m = 1 kg slides down a θ = 30◦ inclined plane from a
height of 5 m. At the bottom of the incline, it collides with
another mass M = 3 kg, and the latter is initially at rest as shown
in Fig. 3. The surface to the right of the inclined plane on which
the 3 kg (green) mass sits is horizontal.
(a) The inclined surface is frictionless. Conserve energy to
find the velocity of the...

Dynamics, please answer all parts.Thank you
Given: Block A has a known constant mass of mA and block B has a known constant mass of ms. The coefficient of kinetic friction between block A and the incline is ex. Both block masses should be considered in your analysis, but the mass of block A is large enough so that block A slides down the incline after starting from rest. You may neglect the masses of the pulleys and cable. It...

3. For experiment A, use equations 1&3 to develop a general equation for the value of tension (T) based on the values of the two masses. You will need this later to answer lab question (4), so write it in now. 4.
