On Sep 26th, 1993, Dave Munday went over the Canadian edge of Niagar Falls in a stell ball and then fell 48 m to the water (and rocks) below. Neglect the effect of the air and determine time and velocity did it take Munday to reach the water?
t = 3.2 s ;
vf = 30.69 m/s
t = -3.2 s ;
vf = 30.69 m/s
t = 9.78 s ;
vf= 96 m/s
t = - 9.78 s ;
vf = -96 m/s
