Projectile Motion and Range Calculation

What is the initial condition of the projectile in the problem?

• It is dropped from a height.

• It is fired at an angle Theta with speed V.

• It is fired horizontally.

• It is fired vertically upwards.

How is the time of flight for the first part of the range (D1) calculated?

• Using the initial speed only.

• Using the total velocity and angle.

• Using the vertical component of velocity and gravitational acceleration.

• Using the horizontal velocity only.

What happens to the projectile's acceleration at the highest point?

• It becomes zero.

• It remains the same.

• It doubles.

• It changes to G divided by 0.81.

Which equation is used to determine the maximum height of the projectile?

• V = U + at

• S = ut + 0.5at^2

• V^2 = U^2 + 2as

• F = ma

How is the new time of flight (T') for the second part of the range calculated?

• By using the horizontal velocity only.

• By using the initial speed and angle.

• By using the new acceleration and maximum height.

• By using the original time of flight.

What remains constant throughout the projectile's flight?

• Time of flight

• Vertical velocity

• Horizontal velocity

• Acceleration

How is the second part of the range (D2') calculated?

• Using the new time of flight and horizontal velocity.

• Using the maximum height and new acceleration.

• Using the original range and angle.

• Using the initial vertical velocity and time.

What is the relationship between the new range (D') and the original range (D)?

• D' is equal to D.

• D' is 0.95 times D.

• D' is half of D.

• D' is twice D.

What is the value of n in the problem?

• 0.9

• 0.95

• 1.0

• 1.9

What concept is primarily used to solve the problem?

• Projectile Motion

• Circular Motion

• Conservation of Energy

• Newton's Laws of Motion
