A Hooke's law spring constant k=7 220 N/m is compressed 12.0 cm from equilibrium using a 1 kg mass starts to move up on a frictionless inclined plane. Find the velocity immediately after it is released. Find its potential energy as it moves up 3 meters.
A spring (k= 570 N/m) is at the bottom of a 39 degree frictionless inclined plane. The spring is compressed 23 cm and a 2.2 kg mass is placed against the spring. The spring is released. Calculate the distance (in meter) up the incline that the mass travels before coming to a stop for the first time.
A horizontal spring with spring constant 30 N/m is compressed by 5 cm by a 10 gram mass. After the mass is released, it accelerates due to the potential energy of the spring. Use conservation of energy to determine what speed the 10 gram mass reaches after being pushed by the spring Answer in units of m/s and round to 3 significant figures
The spring in the figure below has a spring constant of 1150 N/. It is compressed 28 cm, then launches a 200 g block. The horizontal surface is frictionless, but the block's coefficient of kinetic friction on the incline is 0.20. What distance d does the block sail through the air? Enter a numbor 2.0 m 200g 5°
7. A 0.60 kg mass is attached to a light spring with a force constant of 45 N/m and set into oscillation on a horizontal frictionless surface. If the spring is initially stretched 5.0 cm and released from rest, determine the speed of the oscillating mass when the spring is compressed 1.5 cm. A 28.6 cm/s B 36.5 cm/s C 41.3 cm/s D 58.7 cm/s E 31.7 cm/s
A spring with spring constant 28 N/m is compressed a distance of 7.5 cm by a ball with a mass of 201.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 7.5 cm and is also released, leaving the spring at point A....
A wooden block with mass 1.95 kg is placed against a compressed spring at the bottom of a slope inclined at an angle of 35.0degree (point A). When the spring is released, it projects the block up the incline. At point B, a distance of 4.00 m up the incline from A, the block is moving up the incline at a speed of 6.15 m/s and is no longer in contact with the spring. The coefficient of kinetic between the...
A spring whose spring constant is 1000 N/m is compressed by 10 cm. By how much does its mass increase in its compressed state?
he figure, a spring with spring constant k = 170 N/m s at the top of a frictionless incline of angle θ 36". The lower end of the incline is distance D = 1.0 m from the end of the spring, which is at its relax length. A 2.1 kg canister is pushed against the spring until the spring is compressed 0.24 m and released from rest. (a) What is the speed of the canister at the instant the spring...
It takes 25 N to compress a spring a distance of 30 cm. That compressed spring then has a 3kg block placed in contact with it. The spring is released, causing the 3 kg block to accelerate along a frictionless floor. After leaving the spring, the 3kg block continues moving on the frictionless floor until it collides with and sticks to a 5kg block, initially at rest. What is the spring constant of the spring?
