A block with a mass 3.7 kg is sitting on a frictionless ramp with a spring at rhe bottom that has a spring constant of 540 N/m. The angle of the ramp in respect to the horizontal is 36 degrees.  1) the block starts from rest and slides down the ramp a distance of 69cm before hitting the spring. how far is the spring compressed as the block comes to momentary rest? 2) after the block comes to rest the spring pushes the block back up the ramp. how fast is the block moving right after it comes off the spring.  3) what is the change in gravitational potential energy between the original positiion of the block at the top of the ramp and the position of the block when the spring is fully compressed?

The block of mass 0.5 kg is pushed against a horizontal spring and the spring is compressed by x. After it is released it moves along frictionless horizontal surface and reaches the point A with a speed of v A = 11.0 m/s. The block experiences an average friction force of 6.0 N while sliding up the circular track. The radius of the track R=1.0 m. Can the block pass the top point (point B) without fall off of the track? R k mWWW No. It will fall off before reaching the top. No. The block will reach the top, but it will fall off the track. Yes. The block can safely turn the track. The block can only climb the quarter of the track. Can not determine with the given information Gönder Google Formlar üzerinden asla şifre göndermeyin. O O O O

The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists have studied the change in length of the knee extensor tendon in sprinters and nonathletes. They find (on average) that the sprinters’ tendons stretch 41 mm, while nonathletes’ stretch only 33 mm. The spring constant for the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes?

A 4.4 × 105 kg subway train is brought to a stop from a speed of 0.55 m/s in 0.54 m by a large spring bumper at the end of its track. What is the force constant k of the spring in N/m?

You attach a 2.10 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by 0.300 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches a speed of zero again 0.100 s after release (for the first time after release). What is the maximum speed of the weight (in m/s)? m/s Need Help? Read It Submit Answer

A spring k = 200N / m is fixed at the lower end of a plane with a 37 ° inclination and a friction coefficient m = 0.4. A block with M1 = 1kg is ejected from point A of the plane at a speed of 5m / sec. a-) How fast does the block hit end B of the spring? b-) how much compresses the spring at most?

A block of mass 2.9 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 470 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 13°.  a) The block, starting from rest, slides down the ramp a distance 54 cm before hitting the spring. How far, in centimeters, is the spring compressed as the block comes to momentary rest?  b)  After the block comes to rest, the spring pushes the block back up the ramp. How fast, in meters per second, is the block moving right after it comes off the spring?  c) What is the change of the gravitational potential energy, in joules, between the original position of the block at the top of the ramp and the position of the block when the spring is fully compressed?

A horizontal spring on a frictionless surface with a spring constant of 40 N/m is compressed 0.3 m away from equilibrium and it is held at rest. A 2 kg mass is attached at the end of the spring. The spring-mass system is released from rest. Calculate the initial elastic potential energy stored in the spring before it was released.

A 25-kg child uses a pogo stick to bounce up and down. The spring constant, k, of the toy equals 8750 N/m. a) By how much would the spring be compressed by the child if she simply balanced herself vertically on the pedals of the stick? b) How much energy is stored in the spring under this circumstance?

A ball is attached to a vertical spring with a spring constant of 6.0 N/m.it is held at the equilibrium position of the spring and then released. it falls 0.40m and then bounce back up again. Calculate the mass of the ball
