Question

3.
A particle is thrown vertically upwards from the surface of earth and it reaches to a maximum hight
equal to radius of earth. Velocity of projection is (g is acceleration due to gravity)
a) VSR
b) 28R
c) 4R
d) 5GR​

Answer 1

The maximum height of the projectile is when the projectile reaches zero vertical velocity. From this point the vertical component of the velocity vector will point downwards. The horizontal displacement of the projectile is called the range of the projectile and depends on the initial velocity of the object.
