- Q1
A gun shoots a bullet with a velocity of 500. m/s. The gun is aimed horizontally and fired from a height of 1.50 m. How far does the bullet travel?

277.20 m

275.64 m

276.20 m

276.64 m

30s - Q2
Which of the following conditions applies to a projectile at its highest point?

vertical velocity is zero

vertical velocity is greater than the horizontal velocity

vertical velocity is equal to the horizontal velocity

horizontal velocity is zero

15s - Q3
Which of the following represents the shape of the trajectory of a projectile?

hyperbolic path

parabolic path

circular path

straight path

15s - Q4
What is the acceleration of a projectile in the horizontal direction?

-9.8 m/s

^{2}0 m/s

9.8 m/s

^{2}0 m/s

^{2}15s - Q5
What is the acceleration of a projectile in the vertical direction?

0 m/s

^{2}-9.8 m/s

^{2}it depends on the initial velocity

it depends on mass of projectile

15s - Q6
Which of the following statements is FALSE?

the time

*t*for the upward flight is the same as the time for the downward flight.Maximum range is attained when a projectile is thrown at an angle of 40⁰.

The height of the projectile at any time t is given by the equation:

h = (v

_{i}sin θ) t-1/2 gt^{2}Range,

*R*is equal to the product of the horizontal velocity component*v*and the total time of flight,_{ix}*t*.20s - Q7
What happens to the vertical velocity of a projectile launched at an angle during its flight?

It remains constant because gravity only affects horizontal motion.

It decreases due to gravity until it reaches its maximum height, then increases again as it falls back down.

It increases due to gravity.

It changes direction due to gravity.

What do you call the motion of an object with constant acceleration?

constant motion

uniform motion

uniformly accelerated motion

motion

15s - Q13
Does air resistance affect projectile motion?

No, air resistance only affects objects that are not in motion.

Yes, air resistance can slow down a projectile and change its trajectory.

No, air resistance has no effect on projectile motion.

Yes, air resistance can speed up a projectile and change its trajectory.

20s - Q14
What is the difference between a projectile launched horizontally and one launched at an angle?

There is no difference between a projectile launched horizontally and one launched at an angle.

A projectile launched at an angle has both horizontal and vertical initial velocity.

A projectile launched at an angle has only horizontal initial velocity.

A projectile launched at an angle has only vertical initial velocity.
