Newtons first law of motion
object in motion stays in motion, object at rest stays at rest unless acted upon an unbalanced force
Answer a is one of keplers 3 laws
First do 1.6 m (how far he jumps) 9.8 m/s (what gravity is measured at) then times 2
= 31.36
Sq root = 5.6
You are exerting 100N. Since there’s no NET force, then there must be exactly 100N pushing exactly back on your 100N to cancel it to exactly zero. Newton's first law states that whether a body is at rest or travelling in a straight line at a constant speed, it will remain at rest or continue to move in a straight line at a constant speed unless acted upon by a force.
Answer:
Explanation:
Given, for girl : Weight or force;
Area of both heels;
For elephant, Weight = Force 
= 2000 kg•f
Area of 4 feet;
Now;
Thus, the girl's pointed heel sandals exert 12.5 times more pressure P than the pressure P exerted by the elephant.
I aspire this helps!
