The acceleration of the air plane is 
<u>Explanation:</u>
Given:
The mass of the air plane = 1492.3 kg
Force of each four engine = 1447.5 N
So, the total force of four engines can be calculated as = 4(1447.5) = 5790 N
The force that acts on the object is equal to the product of mass (m) and its acceleration. It can express by the below formula,
The above equation can be written as below to find acceleration,
Now. Substitute the given values, we get,
The ball rolled for 13.2 s
<h3>Further explanation</h3>
Speed is scalar and no direction
A bowling ball rolls 33 m, with average speed = 2.5 m/s
So elapsed time :
No velocity will not be changed
Why?
According to Newtons 1st law the velocity of a moving object remains unchanged unless a external force affect that.
Answer:
For number 2, it will be 8.
Answer:
hi here is your answer and this is a very important question.
Explanation:
A lever is a rigid bar with three parts: the fixed point around which the bar pivots is the fulcrum: the effort arm (in-lever arm) is the part of the lever to which force is applied; the resistance arm (out-lever arm) is the part that bears the load to be moved.
