The Lamborghini Diablo sports car can accelerate from 0.0 km/hr to 99.2 km/hr in 4.0 seconds. What is the acceleration of this car? Give your answer in units of kilometers per hour/sec. To find the acceleration of the car we have to 
1.   First determine the suitable formula for this word problem. Which is a.   A=vf-vi/t 

Given are: Vf=99.2 km/h Vi= 0.0 km/h T= 4.0sec 

Solution: 
A= 99.2 km/h – 0.0km/h / 4.0 sec 
A = 99.2 km/h / 4 sec 
A = 2.8 km/h/sec 

The first one is sec.-b,,third- that

Ithink a is the answer
