Explanation:

Velocity

False

Explanation:

Because that is not true

the diver's speed is independent of the launch height.

Explanation:

For this exercise we must use Newton's second law

              fr - W = m a

the friction force has the general form

              fr = b v

Let's analyze this equation to find out what happens with the speed of the distant club.

When jumping, the initial speed is zero, so the friction force is zero and has an acceleration equal to the acceleration of gravity, as the speed increases the friction force increases decreasing the acceleration until it becomes zero, when it arrives at this value the velocity it has is called terminal velocity and this velocity remains fixed in relation to the trajectory.

             fr = W

             v = cte

The distance or time in which this equilibrium is reached is relatively fast, so the diver's speed is independent of the launch height.

Velocity is defined as the rate of change of displacement whereas speed is defined as the rate of change in distance with respect to time.

Explanation:

i think it is b from this

velocity. A vector quantity which describes the rate at which an object changes its position. Also referred to as “speed with direction.”

Explanation:

No problem :)

A. Velocity

A. Velocity factors with speed and direction and it's kind of process of elimination from then on. Acceleration isn't a change of direction and velocity isn't a change in acceleration

D. velocity
Velocity depends on speed and direction
