at 10 m/s.
O A. The answer cannot be determined.
B. KE at 10 m/s > KE at 5 m/s
C. KE at 10 m/s < KE at 5 m/s
D. KE at 10 m/s = KE at 5 m/s

28. a stone is projected at a cliff of height h with an initial speed of 42.0 mls directed at angle θ0 = 60.0° above the horizontal. the stone strikes at a, 5.50 s after launching. find (a) the height h of the cliff, (b) the speed of the stone just before impact at a, and (c) the maximum height h reached above the grou
