MCAT Question of the Day
    •

    Q:

    		 A cannonball with a mass of 10 kg is fired from a cannon and moves with an initial velocity of 100 meters per second at an angle of 60 degrees to the horizontal. After travelling a projectile path, the object lands in sand, displacing 36 liters of sand in its crater. Neglect air resistance and assume that g=10 m/s^2. What is the magnitude of the object's initial vertical veolocity? Note: sin(30)=0.5, cos(30)=0.866
    		 

    A

    		 25 m/s

    B

    		 50 m/s

    C

    		 87 m/s

    D

    		 100 m/s
