A 2.50 kg block on a horizontalfloor is attached to a horizontalspring that is initially compressed0.0300 m. The spring has forceconstant 840 N/m. The coefficientof kinetic friction between thefloor and the block is .40. Theblock and spring are releasedfrom rest and the block slidesalong the floor. What is the speedof the block when it has moved adistance of .0200 m from its initialposition (at this poing the spring iscompressed 0.0100m)

A toy gun uses a spring to project a 5.9 g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 14 cm long, and a constant frictional force of 0.026 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 5.4 cm for this launch? (Assume the projectile is in contact with the barrel for the full 14 cm)
A 356 g block is dropped onto a relaxed vertical spring that has a spring constant of k 1.7 N/cm. The block becomes attached to the spring and compresses the spring 12.6 cm before momentarily stopping. What is the speed of the block just before it hits the spring (assume that friction is negligible)? (Your result must be in m/s and include 1 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g-9.8 m/s?.)

Blocks 1 and 2, with masses m₁ and m2, are placed on a frictionless, horizontal table with an ideal spring between then. The blocks are moved together, compressing the spring until it stores 87 J of elastic potential energy. When released from rest, the blocks move in opposite directions. Find the maximum speed of block 1 if m₁ = 7.63 kg and m2 = 4.18 kg. m/s V =
In the figure, a 4.2 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo = 6.3 m/s, the height difference is h = 0.96 m, and Hk = 0.612. Find d. H = 0- Number Units

You attach your 4.58 - kg Physics for Engineers book to a horizontal spring (k = 549 N/m). You then pull the book to a distance of 6.7 cm and released it from rest. If the coefficient of kinetic friction between your book and the surface is 0.31, calculate the block's speed as it passes through its original position.
