A 6.00 kilogram block of ice is located against a horizontal spring that has force constant k = 210 N/m and is compressed 0.038 meter. The spring is released and accelerates the block along a horizontal surface. You can ignore friction and the mass of the spring.
(a) Compute the work done on the block by the spring during the motion of the block from its initial position to where the spring has returned to its uncompressed length.
J
(b) Determine the speed of the block after it leaves the spring?
m/s
In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 3.0 m/s, what minimum initial speed did the player need to give the puck in order for it to reach the teammate
what horizontal force is required to move the crate. If the coefficient of kinetic friction between a 33 kg crate and the floor is 0.26, what horizontal force is required to move the crate at a steady speed across the floor? Which is 84 I just help..
