A spring loaded device imparts an initial vertical velocity of 50 m/s to a 0.15 kg ball. The drag force on the ball is Fd= 0.002v^2, where Fd is in Newtons when the speed v is in meters per second. Determine the maximum altitute h attained by the ball (a) with drag considered and (b) with drag neglected.
determine the magnitude of its total accleration when (a) t=0 and (b) t=2 Whats the solution.
