Margie threw a ball upwards while standing on a platform 65ft above the ground. The trajectory follows the equation:h(t)=-1.5t^
2+42t+65,t seconds . How long will it take for the ball to reach its' peak? Round your answer to the nearest tenth. nothing In the statement "Critical thinking requires reasoned judgments," the word reasoned mean
Initial velocity: v o = 30 m/s h = 75 m h = v o * t + g * t² / 2 75 = 30 · t + 9.8 · t² / 2 75 = 30 t + 4.9 t² An equation is: y = 4.9 t² + 30 t - 75 4.9 t² + 30 t - 75 = 0 t = 1.9 s
