A coin is placed 9.0 cm from the axis of a rotating turntable of variable speed. When the speed of the turntable is slowly increased, the coin remains fixed on the turntable until a rate of 36 rpm is reached and the coin slides off. What is the coefficient of static friction between the coin and the turntable?
Express your answer using two significant figures.
A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
What are the magnitudes of the (a) impulse and (b) average force on the passenger during the collision? If the passenger were to jump upward with a speed of 6.00 m/s relative to the cab floor just before the cab hits the bottom of the shaft, what ..
What are the magnitude and direction of the net force. how long does it take for the police car to catch up with the speeder.
A bird is flying directly toward a stationary bird-watcher and emits a frequency of 1020 Hz. The bird-watcher, however, hears a frequency of 1060 Hz. What is the speed of the bird, expressed as a percentage of the speed of sound?
One mole of an ideal gas is heated so that T = AP2, where A is a constant and P is the pressure. The temperature changes from T0 to 4T0. Find out the work completed by the gas. (Use the following as necessary: T0, P0, and V0.)
Four 6.50 kg spheres are located at the corners of a square of side 0.68 m. Calculate the magnitude and direction of the total gravitational force exerted on one sphere by the other three.
A member of an aircraft maintenance crew wears protective earplugs that reduce the sound intensity by a factor of 350. When a jet aircraft is taking off.
Speedy Sue, driving at 33.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 175 m ahead traveling with velocity 5.10 m/s. Sue applies her brakes but could accelerate only at -2.00 m/s2 because the road is wet. Will there be a co..
A 100-kg halfback running north with a speed of 12 m/s is tackled by a 110-kg opponent running south with a speed of 4.0 m/s. If collision is completely inelastic and head-on, compute the speed of the players just after the tackle.
A glass soda bottle is emptied of soda and filled to the very top with water. A cork is carefully fitted into the top of the bottle, leaving no air between the cork and the water.
A wooden raft has a mass of 92kg. When empty it floats in water (density 1000 kg/m3) with 48 percent of its volume submerged. What mass of sand can be put on the raft without it sinking.
A child and sled with a combined mass of 55.20 kg slide down a frictionless hill that is 7.84 m high at an angle of 26o from horizontal. The acceleration of gravity is 9.80 m/s2. If the sled starts from rest, what is its speed at the bottom of hil..
