Question

What is the acceleration of the race car that moves at constant velocity of 300 km/hr ?

• A. 73.32 $m/se{c}^2$.
• B. 0 $m/se{c}^2$
• C. 63.33 $m/se{c}^2$.
• D. 53.33 $m/se{c}^2$.

Answer 1

Answer: (B)

0 $m/se{c}^2$

Since the car is moving with a constant velocity, so change in the velocity of car is zero i.e. $\Delta v=0$
Acceleration of car $a=\frac{\Delta v}{\Delta t}=0m/s^2$
