A 142 g baseball moving with the velocity of 31.5 m/s toward a spring that has the spring constant of 1450.N/m. When the baseball comes to rest compressing the spring, how much is the spring compressed?

A block of mass 1.3 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. F. x0 (a) A constant friction force of 3.7 N retards the block's motion fr the moment is released. How m is the spring compressed when the speed of the block is a maximum. cm (b) What is the maximum speed? cm/s

A block of mass 1.7 kg is attached to a horizontal spring that has a force constant 1100 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. x = 0 a F x = 0 b (a) A constant friction force of 3.4 N retards the block's motion from the moment it is released. How much is the spring compressed when the speed of the block is a maximum. 0.31 cm (b) What is the maximum speed? cm/s

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance Yo' then helps to support any additional load. Consider a leaf spring constant of 5.35 × 105 N/m, helper spring constant of 3.60 × 105 N/m, and y₁ = 0.500 m. Truck body Yo Axle (a) What is the compression of the leaf spring for a load of 4.10 × 105 N? 0.69 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m (b) How much work is done compressing the springs? J and

A 5.00 kg block is moving at v0 = 6.00 m/s along a frictionless, horizontal surface toward a spring with force constant k = 500 N/m that is attached to a wall. The spring has negligible mass. What is the maximum compression of the spring i.e. how much will the spring compress before the block rebounds?

A 10.0 g bullet is fired into and embeds itself in a 2.30 kg block attached to a spring with a spring constant of 19.8 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block, and the block slides on a frictionless surface? (Note: You must use conservation of momentum in this problem.) m

An object of mass 6.25 kg slides down a hill of height 21.1 m. At the bottom of the hill is a spring with spring constant 53.6 N/m. How far is the spring compressed when the mass comes to rest? Assume the mass starts from rest at the top of the hill. Give your answer in meters to three significant figures.

An elastic cord is 72 cmcm long when a weight of 73 NN hangs from it but is 89 cmcm long when a weight of 210 NN hangs from it.What is the "spring" constant kk of this elastic cord?

A block of mass m 2.00 kg slides along a horizontal table with speed vo 9.50 m/s. At x = 0 it hits a spring with spring constant k95.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by u 0.100. How far has the spring compressed by the time the block first momentarily comes to rest? wwwww.wl Number 9.50 m/s m Ar ?

A 100 kg one-man bobsled starts from rest 50 m from the end of an icy, 15° slope. A giant 2.0-m-long spring is placed against a barricade at the bottom of the slope. (Figure 1) shows a coordinate system with the origin at the base of the spring. The bobsled brake fails to work, and the sled crashes into the spring. The spring compresses 75 cm before expanding and shooting the bobsled back up the slope. What is the spring constant of the spring?
