A body is projected vertically upward and then allowed to fall back down under gravity. Which of the following velocity–time \((v \text-t) \) graphs correctly represents its motion throughout the ascent and descent?

A ball is thrown vertically up (taken as \(+z\)-axis) from the ground. The correct momentum\(\text-\)height (\(p\text{-}h\)) diagram is:

A tennis ball is released from a height \(h\) and after freely falling on a wooden floor it rebounds and reaches height \(\frac{h}{2}\). The velocity versus height of the ball during its motion may be represented graphically by:
(graph are drawn schematically and on not to scale)

The velocity (\(v\)) and time (\(t\)) graph of a body in a straight-line motion is shown in the figure. The point \(S\) occurs at \(4.333\) seconds. The total distance covered by the body in \(6\) s is:

       
1. \(12\) \(\text{m}\)
2. \(\dfrac{49}{12}\) \(\text{m}\)
3. \(11\) \(\text{m}\)
4. \(\dfrac{37}{3}\) \(\text{m} \)

If the velocity-time graph has the shape \(AMB,\) what would be the shape of the corresponding acceleration-time graph?

A scooter accelerates from rest for time \(t_1\) at constant rate \(a_1\) and then retards at constant rate \(a_2\) for time \(t_2\) and comes to rest. The correct value of  \(\frac{t_1}{t_2}\) will be:
1. \(\frac{a_1+a_2}{a_2}\)
2. \(\frac{a_2}{a_1}\)
3. \(\frac{a_1}{a_2}\)
4. \(\frac{a_1+a_2}{a_1}\)
