The ball B has a mass 5 kg and is attached to the end of a 1.7 m long rod whose mass may be negligible. If the shaft is subjected to a torque of M = 3t2 + 2 N.m, where t is in seconds, determine the speed of the ball when t = 3 s. Given, the ball has a speed of 4.8 m/s when t = 0. Present your answers in m/s.

(10%) Problem 5: A ball with an initial velocity of 5.5 m/s and mass 2.5 kg moves at an angle 68° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 68° above the horizontal, moving in the opposite direction with the same speed. See the figure. е 4 What was the magnitude of the impulse delivered by the wall, in kilogram meters per second? Grade Summary Deductions Potential 100% E sin cos...

Problem 5. (20 points) A block of mass 2 kg on top of a table is held at rest against a spring with spring constant 1000 N/m. The spring is initially compressed distance 10 cm. The block is released, slides along the table, then leaves the table and falls 80 cm to the ground. (a) (6 points) Assuming the table is frictionless, calculate the speed of the block just as it leaves the edge of the table. (b) (6 points)...

6. (10 pts) A patient with a broken leg was placed in traction using the system shown below at left. Once the cast is off of the foot, the system can be modeled as shown at right where m is the mass of the cast. In a most unfortunate incident, the cast slips off of the patient's foot and is flung by the traction system. In this problem, model...

2. A mass of m kilograms (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixed to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The...
