A 2.0 kg mass is placed against a spring of force constant 800 N/m, which has been compressed 0.22 m, as illustrated. The spring is released, and the object moves along the horizontal, frictionless surface and up a frictionless slope. Calculate: a) the maximum velocity of the mass. ľ 2.0 kg -0.22 m 0 Ah b) the speed of the mass when it reaches a vertical height of 0.50 m up the slope.

In the figure, a block of rnass m=12 kg is released from rest on a frictionless incline of angle 0 = 30°. Below the block is a spring that can be compressed 2.0 cm by a force of 270 N. The block momentarily stops when it compresses the spring by 5.5 cm. A) How far does the block move down the incline from its rest position to this stopping point ? B) What is the speed of the block just as it touches the spring?

A 1.4 kg mass slides to the right on the surface having a coefficient of kinetic friction 0.25. The object of the speed of v(initial)=2.7 m/s when it makes contact with a light spring that has a force constant of 50 N/m. The object comes to rest after the spring has been compressed a distance d. The object is then forced toward the left by the spring and continues to move in that direction beyond the spring's unstretched position. Finally, the object comes to rest at distance D to the left of the unstretched spring. Find the distance of compression d. Find the speed v at the unstretched position when the object is moving to the left. Find the distance D where the object comes to rest.

A box of mass m = 10 kg moves with a speed Vo= 4.5 m's on a fictioniess horizontal floor as shown in the Figure below.
