Vedclass · Answer

(B) The acceleration due to gravity $(g)$ always acts vertically downwards towards the center of the Earth,regardless of the direction of the body's motion.Since the upward direction is defined as positive,the downward direction must be negative.During the upward journey,the body moves against gravity,but the acceleration is still directed downwards,so it is negative.During the downward journey,the body moves in the direction of gravity,but the acceleration is still directed downwards,so it remains negative.Therefore,the acceleration is negative during both the upward and downward journeys.

$A$ body is projected vertically upward from the surface of the Earth. If the upward direction is taken as positive,then the acceleration of the body during its upward and downward journey are respectively:

Assertion $(A)$: The displacement of a vertically projected body during the last second of its upward motion is $\frac{g}{2}$.
Reason $(R)$: For a vertically projected body,the acceleration decreases gradually and becomes $\frac{g}{2}$ during the last second of upward motion.

$A$ student is throwing balls vertically upwards such that he throws the $2^{\text{nd}}$ ball when the $1^{\text{st}}$ ball reaches its maximum height. If he throws balls at an interval of $3 \ s$,what is the maximum height reached by the balls (in $m$)? (Take $g = 10 \ m/s^2$)
