Two balls are projected at 30o and 60o with same initial velocities. The ratio of their maximum height is

Correct answer: B. 1:3

  • A. 1:2
  • B. 1:3
  • C. 1:4
  • D. 1:√2

Explanation

The ratio will be h1/h2= sin^2(30)/sin^2(60) (as the initial velocities and g are same they are cancelled out) = 1/3Hence B is the correct option.

About Force and Motion

Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
