Answer:  
 
Explanation:
We know that the formula for acceleration is given by:
  , where v = Final velocity
 , where v = Final velocity
u= Initial velocity
Given :  The driver of a car traveling 110 km/h slams on the brakes so that the car undergoes a constant acceleration.
i.e. u=   110 km/h  [∵  1 km= 100 meters and 1 hour = 3600 seconds]
  [∵  1 km= 100 meters and 1 hour = 3600 seconds]
v=  0  m/s ( At brake , final velocity becomes 0)
t=4.5 seconds  
Substitute all the values in the formula , we get

Hence, the average acceleration of the car during braking is  .

Explanation:
F = 20N m= m1 a=10m/s²
 m=m2 a=5m/s²
F = ma
<u>for the first one</u><u>:</u><u> </u>
f=m1 × a
20 = m1 ×10
20=10m1
m1=20/10
m1=2
<u>for</u><u> </u><u>the</u><u> </u><u>second</u><u> </u><u>one</u><u> </u><u>:</u>
f=m2×a
20=m2×5
m2= 20/5
m2= 4
since F=ma
F=(m1+m2) ×a
F =(4+2)×a
F =6×a
F=20(from the question above )
20=6×a
a=20/6
a=3.33
 
        
                    
             
        
        
        
'N' is labelled 'runoff'. That's when the water is down. Streets are wet, worms come out of the ground, and water flows down the street to the sewer.
