1. The problem statement, all variables and given/known data An amusement park game, shown in the figure (see attachment), launches a marble toward a small cup. The marble is placed directly on top of a spring-loaded wheel and held with a clamp. When released, the wheel spins around clockwise at constant angular acceleration, opening the clamp and releasing the marble after making 11/12 revolution. What angular acceleration is needed for the ball to land in the cup? 2. Relevant equations x1 = vcos(theta)t y1 = y(initial) + vsin(theta)t - 4.9t^2 omega = v/r a = (omega(final)^2 - omega(initial)^2)/2(delta(theta)) 3. The attempt at a solution 1) 11/12 of a revolution = 330 degrees, therefore it is launched at an angle of 30 degrees. 2) It is shot from an initial height of rcos30 = 0.2*sqrt3/2 m 3) It has a range of 1 + rsin30 = 1 + 0.2*1/2 = 1.1 m I know I'm supposed to find launch velocity from this data but how do I go about doing so?
