Acceleration = (change in velocity) / (time for the change)
Change in velocity = (ending velocity) - (starting velocity)
Change in the plane's velocity = (10,000 m/s north) - (8,000 m/s north)
Change in the plane's velocity = 2,000 m/s north
Time for the change = 40 seconds
Acceleration = (2,000 m/s north) / (40 seconds)
<em>Acceleration = 50 m/s² north </em>
 
        
             
        
        
        
Answer:
Momentum is define as the product of the mass and velocity of a body. It is measured in Kgm/s.
Explanation:
Momentum is the product of mass and velocity of an object. When an object or a body of mass 'm' is moving with velocity 'v', then its momentum can be determined as;
momentum (P) = mass × velocity
i.e            P = m × v
                   = mv
It is measured in Kgm/s.
The change in momentum of a body is referred to as its impulse (Ft).
ΔP = m(v - u) = Ft
Where: P is the momentum of the object, m is its mass, v is its final velocity, u is the initial velocity, F is the force and t is the time in which the force acts.
 
        
                    
             
        
        
        
Answer:
Kinetic energy decreases as you go up hill
Potential energy increases as you go up hill
 
        
             
        
        
        
Recall that mass is the amount of matter present in a body. That means it's a property that is consistent regardless of the body's current location, gravity's pull on the body, etc. 
Let's not confuse mass with weight (which is a force computed as Weight = mass x acceleration). Mass will remain constant and that means that whether the object is on Earth or on Mars, its mass remains the same.  Thus, the object will still have 2.00 kg as mass on Mars. 
Answers: 2.00 kilograms
