Explorers on a planet with a thin atmosphere want to measure the acceleration of gravity at its surface. So they use a spring gun to launch a ball bearing vertically upward from the surface with a launch velocity of 29 ms. If we denote by gs the acceleration of gravity in that planet, in ms2, then the ball bearing will move following the formula:
s(t) = 30(t) - [gs/2][t^2]
If the ball bearing reaches its maximum height 21 seconds after being launched, what is the value of gs?
