A centrifuge in a medical laboratory is rotating at an angular speed of \( 3600 \) \( \text{rev/min} \). When switched off, it rotates \( 50.0 \) times before coming to rest. Find the constant angular deceleration of the centrifuge.
A rotating, rigid body makes 10 complete revolutions in 10 seconds. What is its average angular velocity?
A train is moving to the right at \( 20 \) \( \text{m/s} \). A passenger on the train throws a ball horizontally to the left at \( 5 \) \( \text{m/s} \) (relative to the train).
Two identical object rests on a platform rotating at constant speed. Object A is at distance of half the platform’s radius from the center. Object B lays at edge of the platform. Assuming the platform continues rotating at the same speed, how does the centripetal force of the two objects compare?
How does the speed \(v_1\) of a block \(m\) reaching the bottom of slide 1 compare with \(v_2\), the speed of a block \(2m\) reaching the end of slide 2? The blocks are released from the same height.
A bird, traveling at \(50 \, \text{m/s}\) wants to hit a man \(100 \, \text{m}\) below with a dropping. How far in distance before flying directly over the man should the bird release it?
A \(100 \, \text{kg}\) person is riding a \(10 \, \text{kg}\) bicycle up a \(25^\circ\) hill. The hill is long and the coefficient of static friction is \(0.9\). The person rides \(10 \, \text{m}\) up the hill then takes a rest at the top. If she then starts from rest from the top of the hill and rolls down a distance of \(7 \, \text{m}\) before squeezing hard on the brakes locking the wheels, how much work is done by friction to bring the bicycle to a full stop, knowing that the coefficient of kinetic friction is \(0.65\)?

Five forces act on a rod that is free to pivot at point \( P \), as shown in the figure. Which of these forces is producing a counter-clockwise torque about point \( P \)?

The elliptical orbit of a comet is shown above. Positions \(1\) and \(2\) are, respectively, the farthest and nearest positions to the Sun, and at position \(1\) the distance from the comet to the Sun is \(10\) times that at position \(2\). What is the ratio \(\dfrac{F_1}{F_2}\), the force on the comet at position \(1\) to the force on the comet at position \(2\)?
A 0.035 kg bullet moving horizontally at 350 m/s embeds itself into an initially stationary 0.55 kg block. Air resistance is negligible.
You kick a soccer ball with an initial velocity directed 53° above the horizontal. The ball lands on a roof 7.2 m high. The wall of the building is 25 m away, and it takes the ball 2.1 seconds to pass directly over the wall.
