Physics · MOTION IN A PLANE

हिन्दी

A cricket ball is thrown with a speed of \( 28\text{ m/s} \) at an angle of \( 30^\circ \) above the horizontal. Taking \( g = 9.8\text{ m/s}^2 \), the maximum height achieved by the ball is:

  1. 5.0 m
  2. 20.0 m
  3. 15.0 m
  4. 10.0 m

Correct answer · Option 4

10.0 m

Explanation

\( h_m = \frac{(v_o\sin\theta_o)^2}{2g} = \frac{(28 \sin 30^\circ)^2}{2 \times 9.8} = \frac{14^2}{19.6} = \frac{196}{19.6} = 10.0\text{ m} \).
