Answer:
the minimun horizontal force is = 5,88 N
Explanation:
Using a free body diagram we can calculate this force, in the image attached and using Newton's law we have:
Answer:
"the" (and any subsequent words) was ignored because we limit queries to 32 words
Since force = mass X acceleration, then the force he excerts on the earth (aka his weight) equals his mass times the force of gravity.
Therefore
W = (66 kg) X (9.8 m/ss)
W = 646.8 kgm/ss
kg m/ss are also known as Newtons, so your answer is...
646.8 N
