A. t = 50 ft/s / 32.2 ft/s²
B. the velocity is zero at the peak
... so the average ascending velocity is 25 ft/s
... the displacement is 25 ft/s multiplied by the time from part A
C. the time is half of the time from part A
... the average velocity is (50 + 25)/2 ft/s
... the height is velocity times time
B. the velocity is zero at the peak
... so the average ascending velocity is 25 ft/s
... the displacement is 25 ft/s multiplied by the time from part A
C. the time is half of the time from part A
... the average velocity is (50 + 25)/2 ft/s
... the height is velocity times time
