PLEASE PLEASE HELP ASAP A cyclist speeds up from 3 m/s to 7 m/s in 8 seconds.

What is its change in velocity?

What's its acceleration?

Change in velocity = 4 m/s and acceleration = 0.5 m/s²

Explanation:

Given that,

Initial velocity, u = 3 m/s

Final velocity, v = 7 m/s

Time, t = 8 seconds

(a) The change in velocity of a cyclist.

(b) Acceleration,

So, the change in velocity is 4 m/s and acceleration is 0.5 m/s².

explanation:

newton's third law, for every action there is an equal and opposite reaction.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.
