Answer:

180 m

Explanation:

The rock follows a free-fall motion - so the vertical distance covered can be found by using the equation

h=\frac{1}{2}gt^2

where

g = 10 m/s^2 is the acceleration due to gravity

t = 6.00 s is the time of the fall

Substituting these data, we find the height of the cliff:

h=\frac{1}{2}(10 m/s^2)(6.00 s)^2=180 m

Can lack of sleep cause muscle injuries?
Talja [164]

sleeps help in muscle recovery, so when we do not sleep or lack of sleep it leads to inflammation in muscles, which causes pain in muscles.

Sleep and pain both have relation.

Poor sleep schedule causes this muscle pain intensity to increase

In addition to inflammation and pain, it also decreases the tolerance of pain.

As we know sleep heals the muscle and fasten any injury caused to muscle, lack of it causes the healing slow.

This inflammation in muscle causes poor performance in the body.

A man applies a force of 100 Newtons to a rock for 60 seconds, but the rock does not not move. What is the amount of work done b
frozen [14]
Well if the rock doesn't move, then there is no amount of work done. There is no work done on an object if a force is applied to the object but it DOES NOT change its position, in this case is the rock.
