mass 128. In all problems assume the lego slides with negligible friction rahe La starts from rest at a height of 23 cm from the ground on a ramp. how fast is it going when it gets to the bottom of the (1) Ir the Lego is pushed up against a spring (k 44.1 kg/s) to an initial compression of 3.5 cm and released from rest, how fast is imoving when it leaves the spring? Assume the spring is completely decompressed when the Leggo leaves the spring and slides on a horizontal surface. rum (C) The Leggo is pushed up against a spring (k - 44.1 kos) with an initial compression of 3.5 cm and released from rest. After Assume the spring is completely decompressed when the Leggo leaves the spring. leaving the spring, the Leggo slides up a ramp. How high does the Legito go up the ramp when it comes to rest on the ramp.
