Can you please answer these

Ay A B A stiff ideal spring has a spring constant of 240 N/m, and a mass that is small enough to be ignored. The spring has an equilibrium length of 2.50 meters but it is compressed the distance "delta y" of 0.5 meters (see diagram) to a length of 2.0 meters and a block of mass 1.02 kg is placed on top of it, as shown in Diagram A, above left. The block is not attached to the spring. When the block is released, the spring expands back to its equilibrium length as shown in Diagram B above. The spring remains at this length and the block continues moving upward into the air, as shown in diagram C. 1) Calculate the work that the spring does on the block as the spring expands from a length of 2.0 meters to its equilibrium length of 2.5 meters (in the time between diagram A and diagram B above). The sign of the work done by the spring (positive or negative) is important. joules Submit

2) Calculate the work that the Earth does on the block (via gravity) as the spring expands from a length of 2.0 meters to its equilibrium length of 2.5 meters (in the time between diagram A and diagram B above). The sign of the work done by the Earth (positive or negative) is important. joules Submit 3) Assuming friction is negligible, calculate the net work done on the block as the spring expands from a length of 2.0 meters to its equilibrium length of 2.5 meters (in the time between diagram A and diagram B above). The sign of the net work (positive or negative) is important. joules Submit 4) Assuming friction is negligible, and assuming the block started from rest in Diagram A, above, calculate the speed of the block as it left the top of the spring, immediately before the image in diagram C, above. m/s Submit
