276.20 m

Question 2

Which of the following conditions applies to a projectile at its highest point?

Accepted Answer

vertical velocity is zero

Answer

vertical velocity is greater than the horizontal velocity

Answer

vertical velocity is equal to the horizontal velocity

Answer

horizontal velocity is zero

Question 3

Which of the following represents the shape of the trajectory of a projectile?

Accepted Answer

parabolic path

Answer

hyperbolic path

Answer

circular path

Answer

straight path

Question 4

What is the acceleration of a projectile in the horizontal direction?

Accepted Answer

0 m/s2

Answer

-9.8 m/s2

Answer

0 m/s

Answer

9.8 m/s2

Question 5

What is the acceleration of a projectile in the vertical direction?

Accepted Answer

-9.8 m/s2

Answer

0 m/s2

Answer

it depends on the initial velocity

Answer

it depends on mass of projectile

Question 6

Which of the following statements is FALSE?

Accepted Answer

Maximum range is attained when a projectile is thrown at an angle of 40⁰.

Answer

the time t for the upward flight is the same as the time for the downward flight.

Answer

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

h = (v_i sin θ) t-1/2 gt²

Answer

Range, R is equal to the product of the horizontal velocity component v_ix and the total time of flight, t.

Question 7

What happens to the vertical velocity of a projectile launched at an angle during its flight?

Accepted Answer

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

Answer

It remains constant because gravity only affects horizontal motion.

Answer

It increases due to gravity.

Answer

It changes direction due to gravity.

Question 8

What angle we get the maximum height in simple projectile motion?

Accepted Answer

90 degrees

Question 9

The angle at which a thrown ball will go the farthest

Accepted Answer

45 degrees

Question 10

The horizontal distance traveled by a projectile within the total time of its flight is called

Accepted Answer

Range

Question 11

It is the motion of objects moving in two dimensions under the influence of gravity

Accepted Answer

Projectile Motion

Question 12

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

Accepted Answer

uniformly accelerated motion

Answer

constant motion

Answer

uniform motion

Answer

motion

Question 13

Does air resistance affect projectile motion?

Accepted Answer

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

Answer

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

Answer

No, air resistance has no effect on projectile motion.

Answer

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

Question 14

What is the difference between a projectile launched horizontally and one launched at an angle?

Accepted Answer

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

Answer

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

Answer

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

Answer

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