During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 120 N to the tire's rim. The mass of the wheel is 1.90 kg and, for the purpose of this problem assume that all of this mass is concentrated on the outside radius of the wheel. The diameter of the wheel is 50.0 cm. A chain passes over a sprocket that has a diameter of 9.00 cm. In order for the wheel to have an angular acceleration of 3.00 rad/s2, what force must be applied to the chain? (Enter the magnitude only.)
A 3.0-kg block sits on top of a 5.0-kg block which is on a horizontal surface. If the force is 10% greater than your answer for (a), what is the acceleration of each block
An electron is projected vertically upward with a speed of 1.65x10^6 m/s into a uniform magnetic field of 0.160 T that is directed horizontally away from the observer. What would the radius of the circle be.
A projectile is thrown from a point 39.2m away from the foot of a building 19.6m high and just reaches the top horizontally. Find the velocity of projection and the angle of throw
A simple pendulum with mass m = 1.5 kg and length L = 2.41 m hangs from the ceiling, What is the magnitude of the radial acceleration as the pendulum passes through the equilibrium point
Assume that, as lying on a beach near the equator watching the Sun set over a calm ocean, you start a stopwatch just as the top of the Sun disappears. You after that stand, elevating your eyes by a height H = 1.90 m.
A 1 kg ball is attached to a 2 m long piece of very light string and suspended in such a way that it can freely swing and it passes just above the ground.
An ideal gas is enclosed in a cylinder that has a moveable piston on top. The piston has a mass of 6200 g and an area of 5 cm2 and is free to slide up and down.
A 0.300 kg ball is thrown vertically upward with an initial speed of 16.0m/s. What is the maximum height reached by the ball
charge of -2.95 µC is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass, which has a radius of 0.097 m. The charges on the circle are -3.85 µC at the position due north and +5.20 µC at the position due ea..
When additional mass is added to the piston, the height of the piston decreases to 16.4 cm. Find out the new pressure applied by the piston.
A particle of mass M moves in one dimension along the positive x axis, under the influence of two forces. The first force is a constant force, with magnitude B and direction toward the origin. The second force is an inverse square law, with magnitude..
A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.875 rad/s. You, with a mass of 72.3 kg, Calculate the total angular momentum of the system.
