Question
1>What is the distance covered by a point object projected with velocity "U" making an angle theta with the horizental?
Joshi sir comment
formula for calculating distance of a curve is ∫ds
where ds2 = dx2 + dy2
and equation of projectile is
y = xtanθ-(1/2)(gx2/u2cos2θ)
try to solve
if not solved give qurey i will give the complete solution
