Our friend Bob is trying to pull a very heavy crate by pulling an attached rope at an angle of 0=0.333 degrees above the horizontal. There exists coefficients of friction u,=0.645, and P={muk} between the crate and the box. The mass of the crate is 386. Using g = 9.81 m/s?, what is the minimum required for that Bob must pull with in order for the box to begin moving? %3D Once you have finished this problem, please also determine with what acceleration the box will be moving immediately after the box begins to slide. You do not need to submit this second portion of the problem.

A coin is resting on the surface of a closed book. As you slowly open the cover, the coin remains in place (it doesn't slide). When the book's cover is open 14 degrees, the coin finally starts sliding down. What is the coefficient of static friction between the book and the coin? Answer to 3 decimal places (e.g. 0.123).
Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.
A student is pulling a crate with a mass of 66.6 kg along a horizontal frictionless floor with a rope that’s inclined at an angle θ = 30.0° above the horizontal as shown. The tension force is measured to be 239 N. What is the magnitude of the normal force on the crate from the floor, in Newtons? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A box of mass ?=24.5 kg is pulled up a ramp that is inclined at an angle ?=19.0∘ angle with respect to the horizontal. The coefficient of kinetic friction between the box and the ramp is ?k=0.345 , and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of ?=2.09 m/s2, calculate the tension ?T in the rope. Use ?=9.81 m/s2 for the acceleration due to gravity.
