What is the time necessary for crossing if the hunter wishes to move neither upstream nor downstream whilst crossing the river?
A disk of radius R = 11 cm is pulled along a frictionless surface with a force of F = 20 N by a string wrapped around the edge. At the instant when d = 26 cm of string has unwound off the disk, what is the torque exerted about the center of the d
A proton moves with a speed of 2.4 106 m/s horizontally, at a right angle to a magnetic field. What magnetic field strength is required to just balance the weight of the proton and keep it moving horizontally?
A spring has a force constant of 595 N/m and an unstretched length of 6 cm. One end is attached to a post that is free to rotate in the center of a smooth table, as shown in the top view below. The other end is attached to a 7 kg disk moving in un
For a damped oscillator with a mass of 290 g, a spring constant 80 N/m and a damping coefficient of 57 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 26 cycles?
Find the pressure exerted on the floor by each leg of the chair, assuming the weight is evenly distributed. Express your answer using two significant figures.
A street lamp weighs 190 N. It is supported by two wires that form an angle of 120° with each other. The tensions in the wires are equal. (a) What is the tension in each wire supporting the street lamp?
A small, 300g cart is moving at 1.60m/s on an air track when it collides with a larger, 5.00 kg cart at rest. After the collision, the small cart recoils at 0.840 m/s. What is the speed of the large cart after the collision?
A 180 , 48.0-cm-diameter turntable rotates on frictionless bearings at 70.0 . A 15.0 block sits at the center of the turntable. A compressed spring shoots the block radically outward along a frictionless groove in the surface of the turntable.
