Two 2 m long pendulums have masses of 600 g and 200 g respectively. At rest,
both masses are in contact. The 600 g mass is lifted up 30° from the vertical line and then released. Calculate the velocity of each mass after the collision.
Suppose e = 0.3.

A 200 g rubber ball is attached to a 1.0 m long string and released from an angle (theta). It swings down and at the very bottom has a perfectly elastic collision with a 1.0 kg block. The block is resting on a frictionless surface and is connected to a 20 cm long spring with spring constant 2000 N/m. After the collision, the spring compresses a maximum distance of 3.0 cm. From what angle was the ball released?

Beginning from rest, an object of mass 200 kg slides down a 9-m-long ramp. The ramp is inclined at an angle of 20o from the horizontal. Air resistance and friction between the object and the ramp are negligible. Let g = 9.81 m/s2. Determine the kinetic energy of the object, in kJ, and the velocity of the object, in m/s, at the bottom of the ramp.

Two blocks with masses 0.443 kg (A) and 0.769 kg (B) sit on a frictionless surface. Between them is a spring with spring constant 26 N/m, which is not attached to either block The two blocks are pushed together, compressing the spring by 0.338 meter, after which the system is released from rest. What is the final speed of the block A? (Hint: you will need to use both conservation of energy and conservation of momentum to solve this problem)....

A pendulum is attached to the ceiling by two 1.7 m long strings. The 30 kg block is composed of wood and can be used to measure the initial speed of a 40 g bullet, by finding the height, h, for the resulting block’s swing after the bullet hits. If the strings attached to the block swing to a maximum angle of 4.7° with respect to the vertical, find A) The potential energy of the system (bullet and block) at...

A jet accelerates at a=3.92 m/s^2 from rest until it reaches its takeoff velocity of 360 km/hr. It has to travel for 5 seconds at its takeoff velocity before taking off. What's the minimum distance that the jet will travel on the runway? A car backs up at a constant speed for a short time, then applies the brakes and steadily comes to rest. Sketch velocity-time and position-time graphs that depict the car's motion. Assume that the forward direction is...
