The motion of a particle is represented by the equation $ S = 8t^3 - 2t^2+ 6t + 7 $ . Find the velocity of the particle at the end of $ 2 $ seconds in $ m s^{-1} $
A body is travelling towards East with a speed of $9\, m / s$ and with an acceleration of $2\, m / s ^{2}$ acting along West on it. The displacement of the body during the $5^{\text {th }}$ second of its motion is
When a particle returns to its initial point, its
A car moving on a straight road covers $ 1/3 $ of the distance with $ 25\,km/h $ and rest with $ 75\,km/h $ . The average speed is
The bus moving with a speed of $42 \,km / h$ is brought to a stop by brakes after $6\, m$. If the same bus is moving at a speed of $90 \,km / h$, then the minimum stopping distance is
The velocity-time graph of particle comes out to be a non-linear curve. The motion is
A car moving with a speed of $50 \,km\, h^{-1}$ can be stopped by applying brakes after moving atleast $6 \,m$. If the same car is moving at a speed of $100 \,km\, h^{-1}$ the minimum stopping distance is
A particle is thrown vertically up with a certain velocity. Assuming the air resistance to be negligible, which one of the following represents the velocity (along $y$-axis) time (along $x$-axis) graph for the entire motion of the particle till it reaches back to the ground
Which of the following cannot be speed-time graph ?
A body is moving with uniform acceleration. covers $200\, m$ in the first $2\, s$ and $220\, m$ in the next $4\, s$. Find the velocity in $m / s$ after $7\, s$.
A body is released from a great height falls freely towards the earth. Another body is released from the same height exactly a second latter. Then the separation between two bodies, $2\,s$ after the release of the second body is, nearly
A charged particle enters a uniform magnetic field with a certain speed at right angles to it. In the magnetic field a change could occur in its
From a balloon rising vertically upwards as $ 5\,m/s $ a stone is thrown up at $10 \,m/s$ relative to the balloon. Its velocity with respect to ground after $ 2\,s $ is (assume $ g=10\,m/s^{2} $ )
If the velocity of a particle is given by $ v=(180-16x)^{1/2}\,m/s$ . then its acceleration will be
