mass of 3.52 kg object is attached to a string. If the force of tension in the string is 52.2 N j, what is magnitude of the object's acceleration?

A stack of two crates is being accelerated upwards by two cables. The cables are directly attached to crate 1 and the tension in each cable is 3248 N. You may assume that the masses of the cables are negligible compared to the masses of the crates. The acceleration of the crates is? bottom crate crate 1 is 109 kg. the top crate is 248 kg.

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.

Two masses are connected to a string whose mass is zero. They are suspended from a pulley that connects two inclined planes. The mass ml is 8.0 kg, and the mass m2 is 12.0 kg. The kinetic coefficient of friction for the two inclined planes is 0.21. a) Determine the acceleration of the two masses. b) Determine the tension of the string. m 34 m₂
