This problem is to let you practice using Newton's second law of motion:

Force = (mass) x (acceleration)

-- The airplane's mass when it takes off (before it burns any of its load of fuel) is 320,000 kg.

-- The force available is (240,000 N/per engine) x (4 engines) = 960,000 N.

-- Now you know ' F ' and ' mass '.  Use Newton's second law of motion to calculate the plane's acceleration.

How do you use vectors daily without realizing it was a vector?<br><br> I need help ASAP !!!
jonny [76]

Explanation:

Vectors are quantities that has both magnitude and direction. A vector is described in terms of quantity and the direction it is headed.

There are different forms of vectors that are used in our daily life.

  • When we describe the motion of a car and the direction it is heading, we are simply talking about its velocity which is a vector.
  • When we say James treks 2km from his school to the house everyday, we are simply describing his displacement.
  • When we apply a force to push the table from one corner of the room to another point, is simply a vector
  • When we change position, it is a vector application.

If a person driving 130 miles per hour and hit a brick wall ? Does the brick wall hit (push) the car back ? Which Newton laws wo
belka [17]

An action of push or pull on an object is force. The two bodies interact with each other. Newton's third law of motion states that every action has equal and opposite reaction. This means that if an object A exerts F amount of force on another object B, object B would also exert the same amount of force on A. when a person driving at speed 130 miles per hour hits wall, the wall would also apply an equal force on car and that would cause the damage to it.
