Derive a formula for the maximum speed vmax of a simple pendulum bob in terms of g, the length L, and the maximum angle of swing ?max.
A ball is thrown horizontally from the top of a tower 30m high and lands 15m from its base. What is the ball's initial speed
A cannonball launched with an initial velocity of 161 m/s at the angle of 45 degrees follows a parabolic path and hits a balloon at the top of its trajectory. Neglect air resistance, how fast is it going when it hits the balloon? What is the accelera..
Two freight cars, each with a mass of 2.9 x 10^5 kg, collide and stick together. One was initially moving at 2.80 m/s and the other was at rest. What is the final speed.
A 12.00 box resting on a horizontal, frictionless surface is attached to a 5 weight by a thin, light wire that passes without slippage over a frictionless pulley. The pulley has the shape of a uniform solid disk of mass 2.5 and diameter 0.560.
A force of 13.3 N pulls horizontally on a 0.9 kg block that slides on a rough, horizontal surface, What is the acceleration of the blocks and What is the tension in the string
A pot of hot water is boiling on your stove. The pot is in the shape of a round cylinder made of aluminum which is 10 cm in radius. The aluminum is 3 mm thick. You notice that after 25 minutes.
A pendulum of length 9.00 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 3m. (That is, 3.0 m is no longer free to swing.) How long does this pendulum take for one o..
Illustrate what constant acceleration does Mary now need during the remaining portion of the race, if she wishes to cross the finish line side-by-side with Sally?
The 200 g head of a golf club moves at 40 m/s in a circular ARC of 1.2 m radius. How much force must the player exert on the handle of the club to prevent it from flying out of her hands at the bottom of swing? Ignore the mass of the club's shaft.
A ball is attached to one end of a wire, the other end being fastened to the ceiling. The wire is held horizontal, Find the velocity (magnitude and direction) of the ball just before the collision
Find a largest image that can be completely imaged on a 35mm film.
From point B, the ball was in the air 2.0 seconds and traveled a horizontial distance of 16.2 meters before hitting the ground. Illustrate with what velocity did the ball leave her hand at point B?
