Question
A ball is thrown from bottom of an incline plane at an angle a from the inclined surface up the plane. Another ball is thrown from a point on the inclined plane with same speed and at same angle a from the inclined surface down the plane. If in the two cases, maximum height attained by the balls with respect to the inclined surface during projectile motion are h1 and h2 then :
Options
A.h1 > h2
B.h1 < h2
C.h1 = h2
D.All the three can be possible
Solution
For both the particles
uy = usin θ and ay = g cos θ
So y motion will be similar for both the particles.
⇒ Maximum height and time of flight will be same for the both. ⇒ h1 = h2
uy = usin θ and ay = g cos θ
So y motion will be similar for both the particles.
⇒ Maximum height and time of flight will be same for the both. ⇒ h1 = h2
