Answer:
Vectors have a size and direction. Each of the existing vector quantity has a magnitude and a direction. Having direction along with the magnitude is the difference of a vector quantity from a scalar quantity. Vectors are indicates with arrows.
 
        
                    
             
        
        
        
Force equals mass time acceleration. Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration.
1.)
Fw (weight) = m (mass) · g (gravity, 9.8 m/s²)
Fw = m * 9.81 m/s²
560N = m · 9.81 m/s²
m ≈ 57.08 kg
2.)
d = 350 meters
t = 65 seconds 
velocity = d/t
velocity = 350 meters / 65 seconds 
velocity ≈ 5.38 meters/sec
3.)
Force = 35N
Distance = 2 meters
Work = Force · Distance 
Work = 35N · 2 meters 
Work = 70 J
 
        
             
        
        
        
'  +4 m/s² ' means that the pigeon's speed is  4 m/s greater every second.
Starting from zero speed, after 10 seconds, its speed is  
                           (10 x 4m/s)  =  40 m/s.
We can't say anything about its velocity, because we have 
no information regarding the direction of its flight.
