Answer:
Kinetic frictional force will be equal to 56.84 N
Explanation:
We have given mass of the skier m = 58 kg
Acceleration due to gravity 
Coefficient of kinetic friction 
We have to find the kinetic frictional force
Kinetic frictional force is given by
So kinetic frictional force will be equal to 56.84 N
Average velocity = displacement / time
In this case, since you move left 60, then right 60, you return to the starting point making the displacement zero.
average velocity = 0 / 60 sec = zero
the average speed is calculated using total distance traveled.
average speed = distance / time
average speed = 120 meters / 60 sec = 2 m/s
Answer:
DMs are not accessible anymore. I assume Zuka is a staff member? the only way to talk to a staff member anymore is to report something, but even then, the probably won't even look at what they're deleting :/
May I have brainliest please? :)
The chemical bonds alow it to pass to the other object.
The kinetic energy of the diver as she hits the water is 159.72J. Details about kinetic energy can be found below.
<h3>How to calculate kinetic energy?</h3>
The kinetic energy of a body can be calculated using the following formula:
K.E = ½ × m × v²
Where;
- K.E = kinetic energy
- m = mass
- v = velocity
According to this question, a 66.0 kg diver is 2.30 m above the water and falls at speed of 2.20 m/s.
Kinetic energy = ½ × 66 × 2.2²
K.E = 159.72J
Therefore, the kinetic energy of the diver as she hits the water is 159.72J.
