Application +4 | -1

A body is thrown at an angle

30^\circ

to the horizontal with the velocity of 30 m/s. After 1 sec its velocity will be (in m/s)

\left( {g = 10\,m/{s^2}} \right).

View answer and explanation

Correct option: A

10\sqrt 7

Option A (

10\sqrt{7}

) is correct because it represents the magnitude of the velocity vector after 1 second, calculated using projectile motion principles.
