The velocity of a body depends on time according to the equation $v = 20 + 0.1{t^2}$. The body is undergoing
Uniform acceleration
Uniform retardation
Non-uniform acceleration
Zero acceleration
The velocity-displacement graph describing the motion of a bicycle is shown in the figure.
The acceleration-displacement graph of the bicycle's motion is best described by
A train moves from one station to another in $2$ hours time. Its speed-time graph during this motion is shown in the figure. The maximum acceleration during the journey is.............$km\, h^{-2}$
The relation between position $( x )$ and time ( $t$ ) are given below for a particle moving along a straight line. Which of the following equation represents uniformly accelerated motion? [where $\alpha$ and $\beta$ are positive constants]
A body is moving with a uniform acceleration covers $40\,m$ in the first $4\,s$ and $120\,m$ in next $4\,s.$ Its initial velocity and acceleration are
On which factors does stopping distance depend ?
