Question

A projectile is thrown with an initial velocity of
(
a
^
i
+
b
^
j
)
m/s
.
If the range of projectile is twice, the maximum height reached by it, then

Answer 1

for range,

a=0

so, s=bt

fo hight,

a=-g,

T=t/2

so, s=ut/4-1/2gt²

according to question,

range =2h,satisfying this ,we will get...

2a-4b=gt
