 P: 35 oh ok, so if i were to have the force constantly be applied perpendicular to the ball than i CAN use the distance formula? if so, lets say the ball has initial velocity 'vi', and a force is applied, the final velocity can be calculated using ${v_f}={v_i}+\frac{Ft}{m}$, could i also calculate the distance travled: $d={v_i}t+\frac{F{t^2}}{2m}$ ?
