A vertical spring (ignore its mass), whose spring constant is 950 N/m, is attached to a table and is compressed down by 0.160 m. A) what upward speed can it give to a 0.380-kg ball when released? B) how high above its original position (spring compressed) will the ball fly?

A box with m = 2 kg is launched up the circular ramp by compressing and releasing a spring with k=5kN/m. If the ramp has ρ=1.5m and the spring is compressed 0.1156 m, will the box be able to reach point B if the coefficient of kinetic friction of the ramp, μk = 0.3?

a) A friend says they have a spring that stretches 5cm every 1 N that is applied. If they stretch the spring to 10 cm (double the distance), how does the spring constant change? b) If given 2 springs, how can you tell which has a greater spring constant without takinG measurements?

A 2.8 kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring, (a) Determine the force constant (in N/m) of the spring, if the box compresses the spring 7.5 cm before coming to rest. N/m (b) Determine the initial speed (in m/s) the box would need in order to compress the spring by 1.4 cm. m/s Additional Materials

A spring with spring constant of 100 N/m launches a 20 g ball verticallyn into the air. If the ball reaches a height of 20 m, determine the original compression distance of the spring.

5) A 2.00-kg block is pushed against a spring with negligible mass and force constant k = 400 N/m, %3D compressing it 0.22 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with a slope of 36.9°. a) What is the speed of the block as it slides along the horizontal surface after having left the spring? 2.00 kg k = 400 N/m wwww b) How far does the block travel up 36.9 ° the incline before starting to slide block?

A block with mass 300 g is held at rest against a spring with spring con- stant 200 N/m that has been compressed 3 cm from its equilibrium length. The block is released and allowed to slide on a table, and the coefficient of kinetic friction between the block and the Problem 1 table is 0.3. The block slides a short distance on the table and then comes to rest. Assume the block loses contact with the spring when the spring is at its equilibrium length, and that the friction force only acts after the block has lost contact with the spring. (a) How much work does the spring force do on the block? (b) How much work does the kinetic friction force do on the block? (c) After leaving the spring, what distance does the block slide before coming to rest? (d) What speed did the block have after sliding 5 cm from the point it lost contact with the spring?
