I need the answer as soon as possible
Time left A ball of mass M= 1 Kg is fired (lLI) from the ground with initial velocity of 20 m/s that makes an angle 30 degrees above the horizontal direction. By ignoring air resistance and by taking ground level to be the reference level for gravitational potential energy, the mechanical energy (in Joules) of the ball when it reaches its highest point is: А. 200 В. 300 C. 400 D. 500 E. Zero
