JEE Main2026Jan 22, Shift 1Physics
Q.

A projectile is thrown upward at an angle 60° with the horizontal. The speed of the projectile is 20 m/s when its direction of motion is 45° with the horizontal. The initial speed of the projectile is _____ m/s.

  1. A

  2. B

    40

  3. C

  4. D

Solution

In projectile motion (no air resistance) the horizontal velocity is conserved. So .

m/s.
