The dimensional formula of acceleration is:

A particle starts from rest and moves along a straight line with an acceleration given by $a = 6t - 4$, where $a$ is in $m/s^2$ and $t$ is in seconds. At what time is the velocity of the particle zero after the start of motion?

Two balls are projected horizontally from the same height with different initial speeds. Neglecting air resistance, which statement is true about their times of flight?

A particle moving with uniform acceleration along a straight line covers distances $S_1$ and $S_2$ in successive time intervals $t_1$ and $t_2$. Which equation correctly relates these quantities?

A ball is thrown horizontally from a cliff edge with velocity $v$. Another ball is dropped vertically from the same point at the same time. Which ball has the greater acceleration at any given instant before hitting the ground (neglecting air resistance)?

Which equation is derived from the definition of acceleration?

The equation of motion $s = ut + \frac{1}{2}at^2$ is derived assuming what condition for acceleration?

A ball is thrown vertically upwards with a velocity of 20 m/s. What is its velocity when it reaches its maximum height?

Two objects of different masses are dropped simultaneously from the same height. Neglecting air resistance, which object will hit the ground first?

A ball is thrown vertically upwards. What is its acceleration at the highest point?
