Question

10.
A particle is projected with a speed V from a point O making an angle of 30° with
the vertical. At the same instant, a second particle is thrown vertically upwards
from a point A. The two particle reach H, the highest point on the parabolic path
30
of particle simultaneously. Then ratio V/v
is
​

Answer 1

Answer:

V/v = 2

Explanation:

A particle is projected with a speed V from a point O making an angle of 30° with  the vertical. At the same instant, a second particle is thrown vertically upwards  from a point A.

Both Particles reach at the peak at same time

so time taken = Equal = T

Vertical Velocity at Peak = 0 m/s

0 = Vsin30 - gT

0 = v - gT

=> Vsin30 - gT = v - gT

=> V(1/2) = v

=> V/v = 2
