Sir Issac Newton developed the Universal law of Gravitation.

<u>Explanation :</u>

With the interesting quest for the answer why does the apply fall from a tree on the Earth, one of the wisest scientists Sir Issac Newton started investigating the action and thus developed the Universal law of Gravitation by estimating what caused the motionless apply to accelerate towards the Earth.  

According to his second law of motions, an objects which are at rest (apply attached to the twig of the tree) could get in motion (fall towards the Earth) only through an external force exerted on him by the Earth. He called this force has “Gravity” or the “Gravitational Force”.

Answer:

F  = 183.153 N

Explanation:

given,

mass of the toothpick = 0.12 g = 0.00012 kg  

initial velocity = 227 m/s    

final velocity = 0 m/s      

penetration depth = 16 mm = 0.016 m        

using the equation of motion        

v² - u² = 2 a s                            

0 - u² = 2 a s                                      

- 221² = 2 × a × 0.016      

a = 1526281.25 m/s²            

Force is equal to            

F = m a

  = 0.00012 × 1526281.25

F  = 183.153 N

A 57-kg woman holds a 6-kg package as she stands within an elevator which briefly accelerates upward at a rate of 0.15g. Determi
Temka [501]

Answer:

R = 710.7N

L = 67.689 N

During gravity fall L = R = 0 N

Explanation:

So the acceleration that the elevator is acting on the woman (and the package) in order to result in a net acceleration of 0.15g is

g + 0.15g = 1.15g

The force R that the elevator exerts on her feet would be product of acceleration and total mass (Newton's 2nd law):

a(m + M) = 1.15g(57 + 6) = 1.15*9.81*63 = 710.7N

The force L that she exerts on the package would be:

am = 1.15g *6 = 1.15*9.81*6 = 67.689N

When the system is falling, all have a net acceleration of g. So the acceleration that the elevator exerts on the woman (and the package) is 0, and so are the forces L and R.
