A 12 kg block is pressed against a spring with spring constant k = 1424 N/m. The spring is normally 65 cm long but the block is pressed against it to compress the spring until it is only 27 cm long. The block is then released and the spring pushes it forward onto a frictionless surface. a)How fast is the block moving immediately after it leaves the spring? b) The mass then slides across a 2.5 m wide surface with...

A horizontal spring with spring constant 130 N/m is compressed 19 cm and used to launch a 2.8 kg box across a frictionless, horizontal surface. After the box travels some distance, the surface becomes rough. The coefficient of kinetic friction of the box on the surface is 0.15. Use work and energy to find how far the box slides across the rough surface before stopping. Express your answer to two significant figures and include the appropriate units.

Problem 2 A 0.5-kg block is pressed a distance d against a horizontal spring of constant 800 N/m. The block sits on a frictionless horizontal surface When the block is released from rest, it slides along the surface, its speed is 1.6 m/s when it leaves the spring (a) Calculate distance d. 4 cm Suppose that the sliding block (speed 1.6 m/s) crosses a rough section of the surface. The leugth of the section is 1m. The block has a...

A spring is used to fire a 100-g block horizontally. The spring has a spring constant of 20 N/m and is initially compressed by 5.0 cm. The block is initially at rest. a) What is the initial elastic potential energy? b) The spring is released. The block leaves the spring when the spring is at its relaxed state. What is the kinetic energy of the block as it leaves the spring? c) After the block leaves the spring, it enter...
An m = 2.0kg block sits next to a compressed spring with spring constant k =...
An m = 2.0kg block sits next to a compressed spring with spring constant k = 4.5N/m. The spring is compressed by x = 3.0m. The spring is released and pushes the box along a surface with no friction. Once freely sliding the block transitions to a ramp with an angle 35 above the horizontal. On the ramp the block experiences a constant force of friction with a coefficient of kinetic friction of μ = 0.15. How far along the ramp’s surface does the block...

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...

A horizontal spring with force constant k = 700 N/m is attached to a wall at one end and to a block of mass m = 2.30 kg at the other end that rests on a horizontal surface. The block is released from rest from a position 3.40 cm beyond the spring's equilibrium position. (a) If the surface is frictionless, what is the speed of the block as it passes through the equilibrium position? m/s (b) If the surface is...
