The velocity-time relation of a particle starting from rest is given by v = kt where k = 2 m/$s^{2}s^2$ . The distance travelled in 3 sec is

If the particle is at rest, then the x – t graph can be only

A body is thrown vertically upwards, maximum height is reached, then it will have

Which of the following is NOT a projectile?

The range of projectile is 1 .5 km when it is projected at an angle of 15° with horizontal. What will be its range when it is projected at an angle of 45° with the horizontal?

Which of the following remains constant for a projectile fired from the earth?

In case of a projectile, what is the angle between the instantaneous velocity and acceleration at the highest point?

A player kicks up a ball at an angle $\theta \backslash theta$ with the horizontal. The horizontal range is maximum when $\theta \backslash theta$ is equal to

The greatest height to which a man can throw a stone is h. The greatest distance to which he can throw it will be

Two balls are projected at an angle $\theta \backslash theta$ and (90° – $\theta \backslash theta$) to the horizontal with the same speed. The ratio of their maximum vertical heights is
