A car starts from a stop sign and accelerates for 10.0 seconds along a straight leveled road ( in a section of road called section 1) till it reaches a speed of 45.00 miles per hour. In the next section (section 2) of the road the car contines to coast for 40.0 seconds at the speed of 45.00 miles/hour. Then in the next section (section 3)the driver applies breaks at 1.50 m/s^2 eventually stopping at the next stop sign.  

 

what is the coasting speed of the car?

 

what is the acceleration of the car in section 1?

 

how far in meters did the car go in each of the sections 1, 2, and 3?

 

what is the average speed in mi/h for the total trip from stop sign to the next stop sign?
