A 1.30-kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Figure a). The object has a speed of vi = 2.60 m/s when it makes contact with a light spring (Figure b) that has a force constant of 50.0 N/m. The object comes to rest after the spring has been compressed a distance d (Figure c). The object is then forced toward the left by the spring (Figure d) and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest a distance D to the left of the unstretched spring (Figure e). k a m b C V = 0 e -D (a) Find the distance of compression d.

A 1.10-kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Figure a). The object has a speed of vi = 2.60 m/s when it makes contact with a light spring (Figure b) that has a force constant of 50.0 N/m. The object comes to rest after the spring has been compressed a distance d (Figure c).

A spring is used to launch a coffee mug. The 20cm long spring can be compressed by a maximum of 8cm. The mug has a mass of 700 g. What kind of spring do you need to launch the mug at least 2 stories high (5 m) - as measured from the relaxed spring position - using the maximum compression? N/m

You push a 2.0 kg block against a horizontal spring, compressing the spring by 15 cm. Then you release the block, and the spring sends it sliding across a tabletop. It stops 75 cm from where you released it. The spring constant is 200 N/m. What is the block–table coefficient of kinetic friction? Draw free-body diagram.

ee 2M Two blocks, of masses M = 4.0 kg and 2M, are connected to a spring of spring constant k = 150 N/m that has one end fixed, as shown in the Figure. The horizontal surface and the pulley are frictionless, and the pulley has negligible mass. The blocks are released from rest with the spring relaxed. What maximum distance does the hanging block fall before momentarily stopping? 1.57 m 2.29 m 1.05 m 1.96 m

In the figure below, a block of m= mass 19 kg is released from rest on a frictionless incline angled of angle theta= 30 degrees. Below the block is a spring that can be compressed 2.0cm by a force of 240 N. The block momentairly stops when it compresses the spring by 5.6cm. A) How far has the block moved down the incline to this stopping point? B) What is the speed of the block just as it touches the spring?

1) A ball of mass m = 300 g is released from rest a at a height h = 45 cm above a vertical spring of force constant k as shown in figure a to the right. The ball strikes the top of the spring and compresses it a distance d = 15 cm as shown in figure b.
