A projectile is fired at an angle of $45°$ and reaches the highest point in its path after $2\sqrt{2}$ s. Find the velocity of projectile in $\mathrm{m}/\mathrm{s}$.

A bomb is dropped by a fighter plane flying horizontally. To an observer sitting in the plane, the trajectory of the bomb is a :

All the graphs below are intended to represent the same motion. One of them does it incorrectly. Pick it up.

A particle is moving along the positive $x$-axis as $x=a\left(t-3\right)+b{\left(t-3\right)}^2+4\left(t-3\right)$, which of the following is true?

The displacement of a particle starting from rest at $t=0$ is given by $s=9t^2-2t^3$. The time in seconds at which the particle will attain zero velocity is

If a particle moves in a curved path, it must have a component of acceleration

If a point charge $q$ is moving in a circle of radius $r$ with speed $v,$ then time period $T$ of the point charge will be

A simple pendulum is oscillating without damping. When the displacement of the bob is less than maximum, its acceleration vector $\overrightarrow{a},$ is correctly shown in which of the following figure ?
