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 man is attempting to lift a crate using a two part pulley system as shown in the image. The crate has mass m2 = 53 kg, and the man has m1 = 75 kg. He pulls downward on the rope with a force of magnitude F = 659 N. The pulleys are massless and frictionless. 1.) Using T to describe the magnitude of the tension force, write an expression for the sum of the forces in the y direction acting on the crate, in terms of gravity and the variables provided. 2.) what is the blocks acceleration in m/s^2?
In the figure below, a block of mass M hangs at rest. The rope that is fastened to the wall is horizontal and has a tension off 52 N. The rope that is fastened to the ceiling has a tension of 91N and makes an angle theta with the ceiling. What is the angle theta? What is the mass M? You MUST draw all the force vectors on the figure with their corresponding unit vectors( i , j ,k ) and then write the relation between forces based your sketches. Show your complete solution
An object weighing 500kg is to be pulled by a man by exerting a force P. Force P is inclined at an angle of 25 deg. measured from the positive axis.

Express your answer in unit of m/s What is the total distance travelled by the object after 5 seconds when the magnitude of P is equal to 8,000 N? Express your answer in unit of m.
You need to think about this assignment a bit. Conversions are needed. The force of friction due to a single rolling wheel or tire is often stated as: Fro = Cr·N where Cr is the rolling resistance coefficient (no units) and N is the normal force. For one single typical car tire, Cr is about 0.015 and a car like a Toyota Camry weighs about 3000 pounds. Consider a Camry driving at constant velocity. The total force of friction acting on the car in Newtons is: Frotal - Total Froll + (1.8 kg/m) v² where the second term is due to air resistance with y measured in m/s. 1. What is the magnitude in Newtons of Frotal When v = 55 miles/hr. 2. What is the magnitude in Newtons of Frotal when v = 70 miles/hr. 3. There has been much debate about a federal law mandating a speed limit of 55 miles/hr. There are many pros and cons to this argument. USING your answers above, describe a physics advantage to driving at 55 miles/hr instead of 70 miles/hr. The INCORRECT answer is that it's safer (it is NOT…
