A particle undergoing simple harmonic motion has an amplitude $A$ and angular frequency $\omega$. What is its average speed over one complete oscillation?

A car travels half the distance with a speed of $v_1$ and the other half with a speed of $v_2$. What is its average speed for the entire journey?

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?

A projectile is launched at an angle $heta$ with the horizontal with an initial speed $u$. If the horizontal range is $R$ and the maximum height reached is $H$, what is the relationship between $R$, $H$, and $heta$?

A body is projected horizontally with a velocity $u$ from a height $h$. If $R$ is the horizontal range and $T$ is the time of flight, which of the following is correct (neglecting air resistance)?

A particle moves in a circular path of radius R. It completes one and a half revolutions. What is the ratio of the distance traveled to its displacement?

The dimensional formula of permeability of free space $\mu_0$ is given by:

The quantity $\sqrt{\frac{\epsilon_0}{\mu_0}}$ has the dimensions of:

A particle moves such that its displacement $x$ varies with time $t$ as $x = At^2 + Bt^3$. The graph of velocity versus time will be:

The position-time graph of a particle is a semicircle with radius $R$. The average velocity of the particle over the entire journey is:
