A bicyclist steadily speeds up from rest to 6.00m/s in 7.30s.
1 answer:
Answer:
21.899 m
Explanation:
The explanation here is a little differe because we are starting from rest. So, everyone does physics a little differently, but what I would start with is trying to find the accelaration. I've given the formula, now you are able to plug this into the displacement formula where you Velocity Initial = 0m/s (Since you are starting from rest) and V final = 6.00 m/s...
You just plug numbers into the formula after solving for accelaration and do some simple algebra! I hope this helps! I am attaching a new pdf for visuals! If you can't open it let me know! Also there is a star by accelaration because I didn't know if I spelled it right, sorry!

Answer:
The correct option is c: 396.9 meters.
Explanation:
First, we need to find the time at which the car landed:
Now, we can find the height of the top-level:
Since the car has only a velocity in the horizontal direction, we have:
Therefore, the correct option is c: 396.9 meters.
I hope it helps you!
Answer:
511.1 J
Explanation:
We are given that
Mass of wood block=m=3 kg
Vertical distance,h=23 m
Horizontal distance =x=30 m
Distance traveled in downward direction y=40 m
Initial velocity,u=0
Where
By work energy theorem
Change in kinetic energy=Work done= mgh-W
Hence, the work done due to friction on the block as it slides down the ramp=511.1 J
Answer:
The outer Ozone is helpful. Ozone occurs in two layers of the atmosphere. The layer closest to the earth's surface is called the troposphere; ground-level or (bad) ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation. It is a main ingredient of urban smog.
