After they are all used up they can’t be renewed or used anymore.
Answer:
So it will lift the mass by h = 17 m
Explanation:
As per energy conservation we know that

here we know that


now we have


so work done by the engine is 250 J
now we have



So, the acceleration of the bicycle is approximately <u>-1.67 m/s²</u> or it can be said to be decelerating approximately <u>1.67 m/s²</u>.
<h3>Introduction</h3>
Hi ! Here I will help material about linear motion changes regularly, which is where you will hear a lot of the term acceleration. Acceleration occurs when an object's speed increases in a certain time interval. Acceleration can be negative which is called deceleration. The relationship between acceleration with velocity and time is manifested in the equation:

With the following conditions :
- a = acceleration (m/s²)
= object's final velocity (m/s)
= object's initial velocity (m/s)- t = interval of the time (s)
<h3>Problem Solving </h3>
We know that :
= object's final velocity = 4 m/s
= object's initial velocity = 12 m/s- t = interval of the time = 4.8 s
What was asked :
- a = acceleration = ... m/s²
Step by step :




So, the acceleration of the bicycle is about -1.67 m/s² or it can be said to be decelerating around 1.67 m/s².
