Assertion is false but Reason is true

(D) When a body reverses its direction,it comes to rest for a moment,for example,a body thrown upward at the topmost point. Hence,the reason statement is correct.In the same example,at the topmost point,the velocity of the particle is $0$,but the acceleration of the particle is equal to the acceleration due to gravity $(g = 9.8 \ m/s^2)$,which is non-zero.Therefore,the assertion statement is false.

$A$ particle is dropped from the top of a tower. The distance covered by it in the last one second is equal to the distance covered by it in the first three seconds. The height of the tower is $....m$

Medium

View Solution

$A$ body falls freely from the top of a tower. It covers $36\%$ of the total height in the last second before striking the ground level. The height of the tower is........$m$

Medium

View Solution

$A$ particle is projected from the ground in a vertically upward direction at $t = 0$,with an initial velocity of $48\, m/s$. The distance travelled by the particle in the $5^{th}$ second is......$m$ $(g = 10\, m/s^2)$.

Water drops fall from a tap onto the floor,$5 \ m$ below,at regular intervals of time. The first drop strikes the floor when the sixth drop begins to fall. The height at which the fourth drop will be from the ground at the instant when the first drop strikes the ground is . . . . . . $m$. $(g = 10 \ m/s^2)$
