Answer:
(a) 15.4 second
(b) 769.23 m
Explanation:
u = 0, a = 6.5 m/s^2, v = 100 m/s
(a) Let t be the time taken
Use First equation of motion
v = u + a t
100 = 0 + 6.5 x t
t = 15.4 second
(b) Let height covered is h.
Use third equation of motion
v^2 = u^2 + 2 a h
100^2 = 0 + 2 x 6.5 x h
10000 = 13 x h
h = 769.23 m
