List of top Physics Questions on Speed and velocity asked in KEAM

A car travels half the distance with a velocity of $20 \text{ kmh}^{-1}$ and another half distance with a velocity of $30 \text{ kmh}^{-1}$ along a straight road. The average velocity of the car in $\text{km h}^{-1}$ is
A bus covers half of the total distance with a speed of 30 kmh\(^{-1}\) and other half with a speed of 60 kmh\(^{-1}\). The average speed during the total journey is
The area under the velocity-time graph of a particle is equal to its
If a particle executing simple harmonic motion with period \( T \) and displacement \( x = A \cos(\omega t) \), then the acceleration and velocity of the particle at the time \( t = \frac{T}{2} \) are respectively:
When a body starts from rest and moves with a constant acceleration, the velocity- time graph for its motion is
The stopping distance of a moving vehicle is proportional to the
A hammer is dropped into a mine. Its velocities at depths d, 2d and 3d are in the ratio
The velocity of a moving particle at any instant is $\hat{i} + \hat{j}$. The magnitude and direction of the velocity of the particle are 
A physical quantity A on multiplication with velocity results in another quantity B. If the quantity B is energy, then the quantity A is
A packet is dropped from a flight ascending with a velocity at height of 10 km. If the packet takes 100 s to reach the ground,^then the velocity of the flight is (Take = 10 ms$^{-2}$ )
The slope of the tangent drawn on position-time graph at any instant is equal to the instantaneous
The variation of speed (in m/s) of an object with time (in seconds) is given by the expression $V(t) = V_0 - 5t + 5t^2$
The apparent frequency observed by a moving observer away from a stationary source is $20\%$ less than the actual frequency. If the velocity of sound in air is $330 \; ms^{-1}$ , then the velocity of the observer is
