Expert Solution
Step 1

Given data:

Mass of the car is,

m= 15500 kg

Initial velocity of the car is,

u= 5.7 m/s

Force applied is,

F= 1300 N

Formula used:

 According to Newton's second law of motion,

F=ma

According to Kinematical equation of motion,

v=u+at

Where, 

u- initial velocity,

a- Acceleration

t- Time
