Speed v = initial speed u + acceleration a x time t 
v=u+at = 2 + 4*3 = 14 m/s
        
             
        
        
        
Answer:
speed of truck (v) =  22 m/s ,
angle of hill (Θ) =15°
Find 
Vertical component (Fv) = ?
Harizontal component (Fh) =?
                Vertical component (Fh) = V cosΘ
                                                         = 22. cos 15
                                                         = 21.25 m/s.
                Harizontal component (Fv) = V sinΘ
                                                             = 22. sin 15
                                                             = 5.69 m/s.
