Question

If R and h represent the range and maximum height respectively of an oblique projection whose start point ( i.e. point of projection ) and end point are in same horizontal level . Then
$r {}^{2} \div 8h \: \: + 2h \: \: \: \: represents$
(A) maximum horizontal range
,(B) maximum vertical range
(C) time of flight
( D ) velocity of projectile at highest point

Answer 1

Final Answer :B) Max horizontal Range.

Steps and Understanding :
1) We know that, In projectile Motion.
Range = u^2 sin(2a) / g
H = u^2 sin^2(a) / 2g

2) We will substitute these values in given equation.

Answer 2

Answer:

here is your answer
