A horizontal spring with a 2 kg mass attached and a, Ask an Expert

Academics

a horizontal spring with a 2 kg mass attached and a springconstant k=300 N/m is compressed 10 cm from its equilibrium position.

a) how much work is done compressing the spring?

b) how much work is down compressing the spring an additional10cm?

c) how fast would the mass be moving if the spring were nowreleased and the velocity of the block was measured each time theblock passed the 7.5cm mark?
