A can of beans that has mass M is launched by a springpowered device from level ground. The can is launched at an angle of a0 above the horizontal and is in the air for time T before it returns to the ground. Air resistance can be neglected. (a) How much work was done on the can by the launching device? (b) How much work is done on the can if it is launched at the same angle a0 but stays in the air twice as long? How does your result compare to the answer to part (a)?
