a tennis ball is dropped from the top of a building . it took 27 seconds to hit the ground. what is the distance
Answer (1)
d = (1/2)at²a = g = 9.81m/s²d = (1/2)(9.81)(27²)d = 3575.745mAlternative Solution:Vi = 0m/sVf = Vi + at Vf = 0 + 9.81*27Vf = 264.87m/sd = (Vi + Vf)(t/2)d = (0 + 264.87)(27/2)d = 3575.745m
