Question #247138

Ari dropped a golf ball from her second story window. The ball starts from rest

and hits the sidewalk 1.5 s later with a velocity of 14.7 m/s. Find the average

acceleration of the golf ball.

Expert's answer

"a_{avg}=\\dfrac{v-v_0}{t}=\\dfrac{14.7\\ \\dfrac{m}{s}-0}{1.5\\ s}=9.8\\ \\dfrac{m}{s^2}."
