Problem 1
A 1130 kg car is held in place by a light cable on a smooth (frictionless) ramp that makes angle 25 above the horizontal .The cable makes an angle 31 above the surface of the
ramp as shown in the figure below
a.Draw the free-body diagram for the car
b. Find the tension in the cable
c.Find the force of the surface of the ramp pushes on the car (i.e. find n
Problem 2
Blocks A, B , and C are connected together by a massless ropes as shown in the figure below. The coefficient of kinetic friction between each block(A and B) and the surface is 0.35. Block C moves down with constant velocity
a-Draw the free- body diagrams for the blocks A,B, and C
b-Find thetension in the rope connecting blocks A and B
c-Find the weight of block C
d-If the rope connecting blocks A and B is cut, what would be the acceleration of C
