A ball is rolled off a table with an initial horizontal speed of 5 m/s. Neglecting air resistance, the time it takes to hit the ground depends on:
The horizontal speed
The height of the table
Both the horizontal speed and height
Neither the horizontal speed nor the height
If two objects are dropped from the same height, one being dropped vertically and the other given a horizontal velocity, they will:
Hit the ground at the same time
Hit the ground at different times
Depend on their masses
Depend on their horizontal velocities
The horizontal velocity of a projectile remains constant because:
Gravity does not act in the horizontal direction
There is no air resistance
Gravity cancels horizontal forces
Both A and B
For a ball rolling off a table, its horizontal displacement depends on:
Initial horizontal velocity and height
Initial vertical velocity
Height only
Mass of the ball
A projectile launched horizontally will experience:
Constant acceleration downward
Constant speed in both directions
Increasing speed in the horizontal direction
No acceleration
If the height of a table is doubled while keeping the horizontal speed constant, the time of flight:
Increases
Decreases
Stays the same
Depends on the mass
A marble is launched horizontally at 10 m/s. Ignoring air resistance, what is its vertical acceleration during its flight?
0 m/s²
-10 m/s²
-9.8 m/s²
Depends on the mass
The range of a projectile launched horizontally from a certain height depends on:
Horizontal velocity and height
Vertical velocity
Mass of the object
Height only
At the peak of its trajectory, the vertical velocity of a horizontally launched projectile is:
Zero
Maximum
Equal to its initial velocity
Does not exist for horizontal motion
Two balls are launched horizontally from the same height but with different speeds. Which hits the ground first?
The faster ball
The slower ball
They hit the ground at the same time
Depends on their masses
For a projectile launched at an angle, the horizontal velocity:
Increases due to gravity
Decreases due to gravity
Remains constant
Depends on the launch height
The maximum height of a projectile depends on:
Its initial vertical velocity
Its initial horizontal velocity
Both horizontal and vertical velocities
Its mass
The horizontal range of a projectile is maximum when the launch angle is:
30°
45°
60°
90°
At the top of its trajectory, a projectile’s vertical velocity is:
Zero
Maximum
Equal to its horizontal velocity
Half of its initial velocity
For a projectile launched at an angle, its time of flight is determined by:
Initial speed and angle
Mass and angle
Only its angle
Horizontal velocity
A projectile launched at a certain angle has its maximum height when:
Vertical velocity is zero
Horizontal velocity is zero
Both vertical and horizontal velocities are zero
Vertical velocity equals horizontal velocity
The total time of flight for a projectile depends on:
Vertical motion only
Horizontal motion only
Both vertical and horizontal motions
None of the above
If air resistance is ignored, the trajectory of a projectile is:
A straight line
A parabola
A hyperbola
A circle
For a given initial speed, the maximum range occurs at:
45°
30°
60°
90°
A projectile launched at 60° has the same range as one launched at:
30°
45°
90°
15°
