Question

Which of the quantities are zero throughout the flight?

A) Velocity
B) Acceleration
C) Altitude
D) Air resistance

Answer 1

Throughout the flight, the quantities that are zero are velocity, acceleration (in the horizontal direction), altitude, and air resistance.

Step-by-step explanation:

Throughout the flight, the quantities that are zero are:

A) Velocity: The horizontal component of velocity remains constant, but the vertical component of velocity becomes zero at the highest point of the trajectory.

B) Acceleration: The acceleration in the horizontal direction remains zero throughout the flight, while the acceleration in the vertical direction is always equal to the acceleration due to gravity (9.8 m/s2).

C) Altitude: The altitude is zero at takeoff and again at the moment of landing.

D) Air resistance: Assuming negligible air resistance, air resistance is considered to be zero throughout the flight.a
