Question

3. As shown in the figure below, a ball of mass 10 kg is fired upwards from the ground, at an initial velocity of 50 m/s, What is the maximum height the ball will reach if (a) atmospheric resistance is neglected; and (b) atmospheric resistance is measured as FD = (0.02v2) N, where v is the speed of the projectile at any instant, measured in m/s.
