The displacement of a particle as a function of time is shown in Figure. It indicates :-
The particle starts with a certain velocity, but the motion is retarded and finally the particle stops
The velocity of the particle is constant throughout.
The acceleration of the particle is constant throughout.
The particle starts with a constant velocity, the motion is accelerated and finally the particle moves with another constant velocity
The motion of a particle along a straight line is described by equation $x = 8 + 12t -t^3$ where $x$ is in metre and $t$ in second. The retardation of the particle when its velocity becomes zero is.......$ms^{-2}$
For a particle projected vertically upwards under gravity travels equal distance during $5^{th}$ and $6^{th}$ second of its motion. Find its projection speed........$m/s$ $(g = 9.8\,m/s^2)$
A point moves with uniform acceleration and $V_1,V_2$ and $V_3$ denote the average velocities in the threesuccessive intervals of time $t_1, t_2$ and $t_3$. Which of the following relation is correct ?
The velocity of bullet is reduced from $200\; m / s$ to $100\; m / s$ while travelling through a wooden block of thickness of $10 \;cm$ . The retardation assuming to be uniform, will be ...........$\times {10^4}\, m/s^2$
A man is, $d$ distance behind a bus. The bus moves away from the man with an acceleration $a$. At the same time, man starts running towards bus with a constant velocity $v$.
