A light spring having a force constant of 125 N/m is used to pull a 8.60 kg sled on a horizontal ice rink. The coefficient of kinetic friction between the sled and the ice is 0.200. The sled has an acceleration of 2.27 m/s2. By how much does the spring stretch if it pulls on the sled horizontally? By how much does the spring stretch if it pulls on the sled at 30.0∘ above the horizontal?

A spring with a spring constant of 1500 N/m is attached to a block of mass 40 kg. If the spring is used to slide the block horizontally across a surface with a static coefficient of friction of 0.6 and a kinetic coefficient of 0.4, how much with the spring stretch before the block begins to move? How much will it stretch if the block is moving at a constant speed?

GOAL Apply the basic definitions of work done by a constant force. PROBLEM An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force of 1.20 102 N on the sled by pulling on the rope. (a) How much work does he do on the sled if the rope is horizontal to the ground (θ = 0° in the figure)...

A light spring of force constant 3.90 N/m is compressed by 8.00 cm and held between a 0.250 kg block on the left and a 0.520 kg block on the right. Both blocks are at rest on a horizontal surface. The blocks are released simultaneously so that the spring tends to push them apart. Find the maximum velocity each block attains if the coefficient of kinetic friction between each block and the surface is the following. In each case, assume...

Problem 5 A spring with a spring constant k=200 N/m is used as a launcher for a small block whose mass is 10 g. The block is placed against the compressed spring in a horizontal arrangement on a smooth horizontal surface. The spring, with the block, is compressed 5 cm and then released. a) Find the speed of the block just as it leaves the spring b) The block encounters a rough surface as it leaves the spring. How much...
A m= 2.00 kg block is pushed against a spring with negligible mass and force constant k= 300. N/m
A m= 2.00 kg block is pushed against a spring with negligible mass and force constant k= 300. N/m, compressing it d= 0.250 m. When the block is released, it moves along a frictionless, horizontal surface and then up an incline with slope 37.0° and a coefficient of kinetic friction of 0.320. A)What is the speed of the block as it slides along the horizontal surface after having left the spring?B) How far does the object travel up the incline before...
