1.A car is moving with a constant speed 18m/s for 10 minutes, how far this car moves in the 10 minutes? Then the car is closing to a stop sign, the car from 18m/s to stop in 3s. What’s the car's acceleration?

2.A car is leaving a stop sign, it is speeding up from rest with an acceleration 5m/s2, how many seconds does the car need to reach 18m/s?

3.A race car is speeding up from 35m/s at an acceleration 15 m/s2. What its velocity of the car after 5 seconds?

4.An airplane is from 50m/s to 100m/s at an acceleration of 20m/s2. How long does it reach that velocity? If it continues accelerates 4 seconds, what is its velocity?
