2. TASK:
450mm

3. EQUATION OF MOTION (TAKING
INTO ACCOUNT AIR RESISTANCE)
Integrate with
respect to t (twice)
Giving the Equation of
Motion of the Trajectory!
From Newton’s 2nd Law
:
r – radius of sphere
v – velocity of sphere
c1 – constant

4. PROJECTILE FIGURES:
Mass = 25g
Radius = 0.02m
KE = 0.0994J
Θ=45º
(for maximum range)

5. LAUNCH MECHANISM

6. ENERGY TRANSFER
In the limiting case:
This the equivalent rpm ‘lost’ in
accelerating the ball.
Therefore minimum rpm needed:
