Q1- (30 points)
During a physics lab, the student ask to add water to a bucket connect by a negligible mass rope to an 80.0 kg car which is positioned on a track which is inclined 15.00above the horizontal. The idea is illustrated in figure. Consider we are using a frictionless pulley. If the coefficient, between the car and the track is 0.200:

a- Draw the free body diagram and write the Newton’s second law equation for each body, car and bucket. (5 points) b- What mass of water would be needed to start the car moving up? (10 points) c- With friction present, suppose water is added until the car is just about move (calculated in part b). Now an additional 4.00 kg of water is added to the bucket with …show more content…
(7 points) b- What kind of collision took place in between the block and the stone? Explain. (7 points) c- Find the maximum distance that the block will compress the spring after the collision. (7 points) d- Calculate the impulse of the block from the moment just after the collision to the moment when it the maximum compression of the spring occurs.(6 points) e- Identify and classify all forces acting on the block the moment when it the maximum compression of the spring occurs. Explain. (3 points) Extra Credit: f- A net force of 6 N acts on an object initially at rest for 0.25s and gives a final speed of 5 m/s. How could a net force of 2 N produce the same final speed?. Explain. (3 points)

A 5.0 kg and 2.0 m beam is hinged to a wall and supported by a thin cable attached to a building. The beam is supported at an angle of 400 as showed in the figure and used to support a 10 kg sign.

a- Draw the free body, diagram showing all forces. (5 points) b- Write the equilibrium, conditions applied to this situation (include each equation and the respectively lever arm for each force). (5 points) c- Calculate the tension in the cable. (7 points) d- Calculate the magnitude, of the compressive force exerted by the beam on the wall. (7 points)
