Your answer is B, or the second one with the squiggly line.

Whenever there is a change in velocity, either due to a change in speed or a change in direction, there will be non-zero acceleration. ... Acceleration is not constant if the net force is not constant.
hope that helps! mind to mark me brainleist
Answer:
Its state is in uniformly accelerated motion
Explanation:
When an object is acted upon the force of gravity only, we said that the object is in free fall.
According to Newton's second law of motion:
where F is the net force on an object, m is its mass, a its acceleration, when the net force on an object (F) is non-zero, than the object accelerates (because a is non-zero), so the object is in accelerated motion.
In case of free fall, the rate of acceleration of the object is equal to , the acceleration due to gravity, and it is constant. So, the object is moving by uniformly accelerated motion.
Answer:
Explanation:
We just have to calculate what angular displacement a ball with an average angular velocity of 290 rev/min experiments in 0.64s. By definition, angular velocity is the angular displacement divided by the time elapsed:
Since and , we can covert:
Where the terms between parenthesis are equal to 1, so they just change the units. Then for our values we have:
