Motion in a Plane
56 questions, each with its answer.
-
A ball is projected with a velocity, $10\ ms^{-1}$, at an angle of $60^\circ$ with the vertical direction. Its speed at the highest point of its trajectory will be :At the highest point, only the horizontal component of velocity remains. Angle with the horizontal $\theta = 90^\circ - 60^\circ = 30^\circ$ $u_x = u\cos\theta = 10\cos 30^\circ = 5\sqrt{3}\ ms^{-1}$
That is every medium question from 2022 in Motion in a Plane.
