According to Newtons third law of motion when one object exerts a force on a second object what is true about the forces?
fomenos

Answer:

D.They are equal in magnitude and opposite in direction

Explanation:

  • Newton's third law states that the action force is always associated with a reaction force.
  • When a body 'A' exerts a force on body 'B', it is called the force of action.
  • When the body 'B' in turn resist the force of 'A' is called the reaction force. It is the reactive force acted upon by the body 'B' on 'A'.
  • This reaction force is equal in magnitude of the action force.
  • If the two bodies remain in the same horizontal line, the 'A' exerts a force in the direction towards 'B' and the body 'B' exerts a reaction force in the direction towards 'A'.
  • Hence, the two forces that are exerted by the bodies are equal in magnitude and opposite in direction.

Derive a general formula for projectile motion with the object launched at an angle
vagabundo [1.1K]

Answer:

  y = x tan θ - (g / 2v₀² cos² θ) x²

Explanation:

An equation is called a general formula that relates the position on the x-axis and the height on the body's axis.

Let's write the position on each axis

X axis. No acceleration

         x = v₀ₓ t

Y Axis.  There is the acceleration of gravity

        y = v_{oy} t - ½ g t²

Let's clear the time in the first equation and substitute in the second

       y = v₀ sin θ  (x / v₀ₓ) - ½ g (x / v₀ₓ)²

       y = v₀ sin θ / v₀ cos θ x - ½ g x² / v₀² cos² θ

       y = x tan θ - (g / 2v₀² cos² θ) x²

This is the trajectory equation in projectile launching

How much will the top five winners of nasa’s design contest win?
sashaice [31]

Answer:

\$100,000

Explanation:

<em>The top 5 winners of NASA's design contest winner received amount of  </em>\$100,000<em> </em>(Dollar One hundred thousand)<em>. </em>The respected amount was divided into 5 parts as there were 5 winners as well.

So, the amount was divided among the winners are as follows:

<em>Winner 1 ⇒ </em>\$20,957.95

<em>Winner 2 ⇒ </em>\$20,957.24

<em>Winner 3 ⇒ </em>\$20,622.74

<em>Winner 4 ⇒ </em>\$19,580.97

<em>Winner 5 ⇒</em> \$17,881.10

Hence by adding all of the 5, we will get the answer, which is \$100,000.
