Answer
s = 100km = 100 * 103 m
u = V2 ms-1
v = 11.186 kms-1 = 11,186 ms-1
a = -9.81 ms-2
v2 = u2 + 2as
u = √(v2 - 2as)
V2 = √(111862 + (2 * 9.81 * 100 * 103))
V2 = 11,300 ms-1
s = 100km = 100 * 103 m
u = V2 ms-1
v = 11.186 kms-1 = 11,186 ms-1
a = -9.81 ms-2
v2 = u2 + 2as
u = √(v2 - 2as)
V2 = √(111862 + (2 * 9.81 * 100 * 103))
V2 = 11,300 ms-1
