V=r/t
Speed equals displacement over the time
V=100/9.92=10.08ms^-1
        
                    
             
        
        
        
Less because the ramp is letting off force but i does depend on the way you are going on the ramp
        
                    
             
        
        
        
Answer:
Say a 14 year old girl was at a construction site and she was asked to move something like a 10,000 pound brick( one brick). She would be acting on it as the unbalanced force but they would still not change their position.
so to say the girl would be doing everything she could to move that brick but the brick would still be in that same spot so the unbalanced force (the girl) would be acting on the thing that was at rest but it wouldn't move.
so the unbalanced force would not really be acting on the thing at rest; even though the unbalanced force was doing something to the brick.
( just think about it and you will eventually get it...just imagine in your head...)

Answer:
3.6 x 10⁶ Pa
Explanation:
A = Area of the heel = 1.50 cm² = 1.50 x 10⁻⁴ m²
m = mass of the woman = 55.0 kg 
g = acceleration due to gravity = 9.8 m/s²
Force of gravity on the heel is given as 
F = mg 
Inserting the values 
F = (55) (9.8)
F = 539 N
Pressure exerted on the floor is given as 


P = 3.6 x 10⁶ Pa
 
        
             
        
        
        
When talking about orbits, it would have to be a mixture of both A. and B. since Newton's first law, gravity plays a huge part in an orbit. However, the universal gravitation law also tells us the relationship between two massive objects in orbit. But to choose only one, it would have to be B. Newton's first law
