Awesome, thank you for the tips and catching my mistake. Could you review my corrections and let me know if my answer now seems to be correct? Find velocity after reaches bottom of hill (by conservation of mechanical energy) ( 1/2 * k * x2 ) + ( 1/2 * m * g ) = 1/2 * m * v2 (1/2 * 100 *...

A 1.0 kg block is held in place against a spring with spring constant k = 100 N/m (see the figure, below) by a horizontal external force. The spring is compressed 20 cm. The external force is removed, and the block is projected with some (horizontal) velocity upon separation from the spring. The...
