The shock absorbers in the suspension system of a car are in such bad shape that they have no effect on the behavior of the springs attached to the axles. Each of the identical springs attached to the front axle supports 333 kg. A person pushes down on the middle of the front end of the car and notices that it vibrates through height cycles in 3.3s. Find the spring constant of either spring.
Suppose a muon produced as a result of a cosmic ray colliding with a nucleus in the upper atmosphere has a velocity v = 0.9500c. What distance is this in the muon's frame
A 60-kg basketball is dropped out of a window that is 6.1m above the ground. The ball is caught by a person whose h&s are 1.5m above the ground. Find gravitational potential energy of the ball.
The potential difference between the plates of a capacitor is 137 V. Midway between the plates, a proton and an electron are released. find the initial speed of the proton
1. Chameleons use their tongues to catch their prey. Their tongues typically accelerate at 250 m/s2 for up to 20 ms, then they travel at constant speed for a further 30 ms. During this total duration, of acceleration plus constant motion, of 5..
A toy cannon uses a spring to project a 5.27 g soft rubber ball. The spring is originally compressed by 4.90 cm and has a force constant of 7.90 N/m. At what point does the ball have maximum speed
An observer on the earth sees a light pulse within a space ship moving at a constant speed of one-half the speed of light (0.5c). What speed does the observer measure for the light pulse
Each of the four circuits in the drawing consists of a single resistor whose resistance is either R or 2R, and a single battery whose voltage is either V or 2V. determine the current delivered to each resistor
A swimming pool has dimensions 32 m 11 m and a flat bottom. When the pool is filled to a depth of 2.10m with fresh water, what is the force caused by the water on the end that is 11m.
Two concentric metal spheres are found to have a potential difference of 846.0 V when a charge of 3.186·10-8 C is applied to them. What is the radius of the inner sphere
A certain mass, when hung from a certainspring, causes the spring to stretch by an amount h compared to its equilibrium length. If the mass is displaced vertically from thisequilibrium, it will oscillate up and down with a period Tosc. Find the pe..
Two organ pipes play the same fundamental note (i.e., the same lowest frequency). Pipe A is open at one end and closed at the other. Find the ratio of the lengths of pipe B to pipe A
A stalactite on the roof of a cave drips water at a steady rate to a pool 3.8 below. What is the velocity of the second drop when the first drop hits the pool
