STANDARD Physics Projectile Motion MCQ Question
A cricket ball is thrown at a speed of 30 m s⁻¹ in a direction 30° above the horizontal. The time taken by the ball to return to the same level is (Take g = 10 m s⁻²)
2s
3s
4s
5s
Correct Answer
Detailed Explanation
The time taken by the ball to return to the same level is calculated using the formula T = (2u sin θ) / g. Substituting the given values, T = (2 × 30 m s⁻¹ × sin 30°) / 10 m s⁻² = 3s.
