Question 1 of 7
A vertical light spring with spring constant 200N/m is compressed by 0.1m and locked; a 0.05kg ball rests on its top. When released, the ball is launched vertically. Given the elastic potential energy Ep=21kx2, ignoring air resistance and taking g=10m/s2, the maximum height of the ball above its release position is ( ).
