Mixed 2D MotionHardQuestion 5358
Question
A particle is projected at 60° to horizontal with 30 m/s (g = 10 m/s²). Velocity at maximum height is:
- A15 m/sCorrect
- B15√3 m/s
- C30 m/s
- D0 m/s
Correct answer
15 m/s
Explanation
At max height, only horizontal component remains: v = ucos60° = 30×(1/2) = 15 m/s.
