Question

The Ferrari 488 can attain a velocity of $90kmph$ from rest within $3s$. What is the acceleration of this car?

• A. $30m/s^2$
• B. $8.3m/s^2$
• C. $10.2m/s^2$
• D. $5.2m/s^2$

Answer 1

The correct option is B $8.3m/s^2$

Initial Velocity $=0m/s$

Final Velocity $=90kmph=25m/s$

Time Duration $=3s$

Acceleration $=\frac{\text{Final velocity-Initial velocity}}{\text{Time Period}}=\frac{25-0}{3}=8.3m/s^2$
