show work for both questions please!!
A constant force acts on a 5.0 kg object and reduces its velocity from 7.0 m/s to 3.0 m/s in a time of 3.0 s. Determine the force. A 600-Kg car is coasting along a level road at 30m/s. (a) How large is the retarding force (assumed constant) is required to stop it in a distance of 70m2 (b) What is the minimum coefficient of friction between tires and roadway if this is to...

Please show work for each part.
A factory worker pushes a 26.5-kg crate a distance of 4.3 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.27 Suppose the worker pushes downward at and angle of 340 below horizontal. (a) What magnitude of force must the worker apply? (b) How much work is done on the crate by this force? (c) How much work...

For the following problem, show all work. Circle your answers. A box of mass m = 5.0 kg is sitting on a ramp, which is elevated at an angle 0 = 20°, compressing a spring Ar = 0.5 m. The spring is released, causing the box to slide up the ramp. At some point, the spring becomes detached from the box. The total length of the ramp is L = 4.0 m and it has a coefficient of kinetic friction...

Question 8 please-show all work
You are building a mobile. It is connected to the ceiling by a rope. The hanging weights are attached to a massless beam. Use L = 0.25 m, D = 0.5 m, M_1, = 1 kg and M_2 = 1.5 kg. You have a third mass M_3 = 2 kg. Determine the tension in the rope connecting the beam to the ceiling and the location where you attached M_3 if you correctly placed it so...
