Projectile Motion

For a projectile projected at angles and , the horizontal ranges described by the projectile are in the ratio of:
1.
2.
3.
4.

A particle of mass m is projected with velocity v making an angle of 45° with the horizontal. When the particle lands on level ground, the magnitude of change in its momentum will be:

1. $2\mathrm{mv}$

2. $\mathrm{mv}/\sqrt{2}$

3. $\mathrm{mv}\sqrt{2}$

4. zero

A missile is fired for a maximum range with an initial velocity of If then the range of the missile will be:

1.		2.
3.		4.

The horizontal range and the maximum height of a projectile are equal. The angle of projection of the projectile is:

1.		2.
3.		4.

The velocity of a projectile at the initial point is Its velocity (in m/s) at the point is:

1.		2.
3.		4.

A particle moving in a circle of radius with a uniform speed takes a time to complete one revolution. If this particle were projected with the same speed at an angle to the horizontal, the maximum height attained by it equals The angle of projection, is then given by:

1.		2.
3.		4.

A ball is projected with a velocity of at an angle of with the vertical direction. Its speed at the highest point of its trajectory will be:

1.		2.	zero
3.		4.

A bullet is fired from a gun at the speed of in the direction above the horizontal. The maximum height attained by the bullet is:

1.		2.
3.		4.
