Significant digits show the precision of measurements and calculations
Answer:
The answer is number 2 :)
<span>Force = Work done / distance = 4Nm / 2m = 2N</span>
Answer:
Height reached will be 28.35 m
Explanation:
Here we can use the work energy theorem to find the maximum height
As we know by work energy theorem
Work done by gravity + work done by friction = change in kinetic energy

now we will have



so here the height raised by the stone will be 28.35 m from the ground after projection in upward direction
Answer:
D
Explanation:
The bottom of the mountain is not correct because your trying to stop.
The top is of the mountain is when you gain energy.
The middle is when you have the most kinectic energy.
