Question # 1

A ball is dropped from a certain height and another ball is projected horizontally from the same point. Which of the following statement is correct?

Choose an answer

Both hit the ground at the same veloctiy

Both hit the ground at the same speed

The change of velocity during the path for both balls is the same

The change of speed during the path for both balls is the same

When the total displacement is divided by total time taken, we get:

Choose an answer

Velocity

Average speed

Average velocity

None of these

During the projectile motion, the horizontal component of velocity

Choose an answer

changes with time

remains constant

becomes zero

decreases with time

Maximum height of a bullet when fixed at 30 with horizontal is 11 m. Then height when it is fired at 60° is

Choose an answer

22 m

6 m

33 m

7.8 m

Bodies which falls freely under gravity provides good example of motion under:

Choose an answer

Uniform acceleration

Non-uniform acceleration

Uniform velocity

None of these

A body is thrown from a height h with speed u, it hits the ground with speed V

Choose an answer

The value of V is maximum if the body is thrown vertically downward

The value of V is maximum if the body is thrown vertically upwards

The value of V is minimum if the body is thrown horizontally

The value of V does not depend on the direction of which it is thrown

The vertical component of velocity of a projectile during its motion is minimum

Choose an answer

at the time of projection

at the highest point

just before hitting the plane of projection

all of them

What must be changing when a body is accelerating uniformly?

Choose an answer

the force acting on a body

the velocity of the body

the mass of the body

the speed of the body

Work done along a closed path in a gravitational force is:

Choose an answer

maximum

Minimum

Zero

Unity

A body whose momentum is constant must have constant

Choose an answer

Acceleration

Velocity

Force

None of these

The horizontal range of projectile, at a certain place, depends upon

Choose an answer

the mass of the projectile

velocity of projection

angle of projection

angle as well as velocity of projection

Choose an answer

7.71 m s^-2

0.5m s^-2

0.15m s^-2

0.092m s^-2

A change in position of a body from its initial position to its final position is known as

Choose an answer

relative motion

displacement

distance
