# Loop #2

Classical Mechanics Level pending

An object of mass M is droped from an height H and passes through the loop with radius R as shown in the image above. The object passes at point A in the imminence of loosing contact with the track. What is the maximum speed at the highest point of the loop in m/s?

$$R=4$$ [m]

$$M=1200$$ [kg]

$$g=9,81m/s^{2}$$

Assume there's no friction between the track/object and no air resistance.
