A projectile is fired at an angle of $ 45^{\circ} $ and reaches the highest point in its path after $ 2\sqrt2\,s $ . Find the velocity of projectile in $ m s ^{-1} $ ,
A particle moves with a uniform speed $ v $ and time period $ T $ in a circular path of radius $ r $ . If the speed of the particle is doubled, its new time period is
A ball is projected up at an angle $\theta$ with horizontal from the top of a tower with speed $v$. It hits the ground at point $A$ after time $t_{A}$ with speed $v_{A}$ . Now, this ball is projected at same angle and speed from the base of the tower (located at point $P$) and it hits ground at point $B$ after time $t_{B}$ with speed $v_{B}$. Then

Uniform circular motion is an example of
The velocity vector of the motion described by the position vector of a particle, $\vec{r}=\left(2 t \hat{i}+t^{2} \hat{j}\right)$ is given by
A certain vector in the $x y$ plane has an $x$-component of $12\, m$ and a $y$-component of $8\, m$. It is then rotated in the $x-y$ plane so that its $x$-component is halved. Then ifs new $y$-component is approximately
