In an old mechanical child's game, a small block is launched from aspring compressed by a player. The object is to just barely get theblock up a short ramp. The spring has a force constant of 650 N/m;the block has a mass of 0.22 kg. During a particular player's turn,the spring is compressed 3.2 cm with the block at rest. It is thenreleased. The game's surface is highly polished; ignore the effectsof friction.
a) after release, the block moves away from the spring andslides smoothly along the horizontal track. what is the velocityafter leaving the spring (v1)? b) then, it slides 24 cm along a ramp inclined at 22 degrees.what is the velocity after going up this ramp (V2)?
