Hi. I'm super late to answering this question but I'll answer anyway since I got it correct.
Answer:
50 m/s
The speed at which the bicycle accelerates in one second is [tex]50 m/s[/tex].
What is acceleration?Acceleration is the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.
The rate at which velocity changes is called acceleration. Due to the fact that it includes both magnitude and direction, velocity is a vector quantity. As the rate at which velocity changes, acceleration is likewise a vector quantity.
They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration. Acceleration is the term used to describe a change in an object's speed or direction.
Required calculations are,
[tex]\frac{1000}{20} = 50[/tex]
