Let acceleration of lift be a.acceleration of ball with respect to the lift = acceleration of ball with respesct to ground - acceleration of the liftOr, aball(lift) = g - a = 9.8 m/s^2 - a = 32 ft./s^2 - a [ 9.8m = 32 ft. ]displacement s = 6 ft.time taken t = 1 s.initial velocity u = 0s = ut + 1/2 at^2 = 0*1 + 1/2 (32-a)*1*1 = 1/2 (32-a)Therefore, 6 = 1/2 (32-a)Hence a = 20 ft./s^2 Tha ks and regards
Let acceleration of lift be a.
acceleration of ball with respect to the lift = acceleration of ball with respesct to ground - acceleration of the lift
Or, aball(lift) = g - a = 9.8 m/s^2 - a = 32 ft./s^2 - a [ 9.8m = 32 ft. ]
displacement s = 6 ft.
time taken t = 1 s.
initial velocity u = 0
s = ut + 1/2 at^2 = 0*1 + 1/2 (32-a)*1*1 = 1/2 (32-a)
Therefore, 6 = 1/2 (32-a)
Hence a = 20 ft./s^2
