A spring oscillator is designed with a mass of 0.258 kg. It operates while immersed in a damping fluid, selected so that the oscillation amplitude will decrease to 1.00% of its initial value in 8.34 s. Find the required damping constant for the system.
The quantity of charge q (in coulombs) that has passed through a surface of area 2.10 cm2 varies with time according to equation q = 7t3 + 5t + 6, where t is in seconds.
An eagle is flying horizontally at 5.7 m/s with a fish in its claws. It accidentally drops the fish. (a) How much time passes before the fish's speed doubles? (b) How much additional time would be required for the speed to double again?
find the potential energy at each location below. How far from the point of the drop will the rock hit the ground.
Three astronauts, propelled by jet backpacks, push and guide a 115 kg asteroid toward the processing dock, exerting the forces, with F1 = 34 N, F2 = 57 N, F3 = 41 N, θ1 = 30°, and θ3 = 60°
find coefficient of kinetic friction between m1 and shelf.
Friction and air resistance are negligible. Illustrate what speed does the ball have when the cable makes an angle of 30 degrees with respect to the vertical?
Starting in the spring, fruit begins to grow on the outer end of a branch on a pear tree. Define how the center of gravity of the pear growing branch shifts all through the course of the summer.
Two identical spheres are made of conducting material. Initially, sphere 1 has a net charge of 33Q and sphere 2 has a net charge of -18 Q
A 1200 N uniform boom is supported by a cable perpendicular to the boom, as in Figure P8.28. The boom is hinged at the bottom, and a 2000 N weight hangs from its top. Find out the tension in the supporting cable and the components of the reaction ..
A student walks 24 m from her math class and then turns 90° and walks 10 m to her locker, that is directly north of her class. What is her total displacement.
Illustrate what diameter has tip of the hour hand with 100 mil/hr tangential speed? If a 10 inch wide top is spinning at 300 RPM, what is the tangential speed at the widest part?
Jessica's weight is 540 newtons. According to the Third Law, if the Earth pulls on Jessica with a force of 540 N, then Jessica pulls on the Earth with a force of 540 newtons that acts in the opposite direction.though , if Jessica stumbles while rol..
