Question

Race Car A accelerates on a straight track from 0 to 100 kilometers/second in 6 seconds. Race Car B accelerates on a straight track from 0 to 100 kilometers/second in 5 seconds. Compare the velocities and accelerations of the cars during the race.

(Hints: Talk about starting and ending velocity of each car. Talk about the acceleration of each car.)

Answer 1

From the calculation, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude

VELOCITY AND ACCELERATION

The rate of change of displacement is called Velocity. While acceleration is the rate of change of velocity.

Given that  a race Car A accelerates on a straight track from 0 to 100 kilometers/second in 6 seconds.

Since acceleration = $\frac{Change in velocity}{time taken}$

a = 1000(100 - 0)/6

a = 100000/6

a = 16666.67 m/$s^{2}$

And race Car B accelerates on a straight track from 0 to 100 kilometers/second in 5 seconds.

acceleration =  $\frac{Change in velocity}{time taken}$

a = 1000(100 - 0)/5

a = 100000/5

a = 20000 m/$s^{2}$

From the calculation above, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude.

Race car A accelerates at 16666.67 m/$s^{2}$, while race car B accelerates at 20000 m/$s^{2}$
