Q. A string requires a 186 N force in order to break. A 1.50 kg mass is tied to this string and whirled in a vertical circle with a radius of 1.90 m. What is the maximum speed that this mass can be whirled without breaking the string?
Q. A curve on a level road has a radius of 120 meters and is banked at the correct angle for a speed of 20 meters per second. If a car rounds this curve at 30 meters per second, what is the minimum coefficient of static friction between the tyres and the rod needed to prevent skidding?
An indestructible bullet 1.85 cm long is fired straight through a board that is 11.10 cm thick. The bullet strikes board with a speed of 455m/s and emerges with a speed of 279m/s. (To simplify, suppose that the bullet accelerates only while the fr..
A spring with spring constant 14 hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 3.0 and released. The ball makes 17 oscillations in 16 seconds. What is it the mass of ball.
For a damped oscillator with a mass of 380g, the spring constant 120 N/m and a damping coefficient of 76 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 28 cycles.
A rookie quarterback throws a football with an initial upward velocity component of 15.33 and a horizontal velocity component of 20.4. Overlook air resistance.
An ocean liner leaves New York City and travels 20.0° north of east for 199km. How far east and how far north has it gone? In other words, what are the magnitudes of components of ship's displacement vector in the following directions.
Estimate the current in an L-R circuit for t>T if the EMF is (12/T) t for 0
The sport with the fastest moving ball is jai alai, where measured speeds have reached 303km/h. If a professional jai alai player faces a ball at that speed and involuntarily blinks, he blacks out the scene for 100ms. How far does ball move throughou..
A professor's office door is 0.90 wide, 2.00 high, 4.00 thick; has a mass of 30, and pivots on frictionless hinges. A "door closer" is attached to door and the top of the door frame. When the door is open and at rest, the door closer exerts the torqu..
Given that 12g of carbon combines with 16g of oxygen to form carbon monixide, how various grams of carbon monoxide can be made from 48g of carbon and 48g oxygen.
Coherent light with wavelength 600 nm passes through two very narrow slits and the interference pattern is observed on a screen 5.00 m from the slits. The first-order bright fringe is at 4.74 mm from the center of the central bright fringe. For what ..
A car of mass = 1300 travelling at 56.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and car's tires. What is the radius of the turn if = 20.0 (assuming the car continues in uniform ..
