With what acceleration does a racing car move if its speed increases from 144 to 216 km / h in 6 seconds?
| August 3, 2021 | education
These tasks: t (acceleration time of the race car in question) = 6 s; V0 (initial speed) = 144 km / h (in SI V0 = 40 m / s); V (speed of the racing car after acceleration) = 216 km / h (in SI V = 60 m / s).
The acceleration with which the considered racing car is moving, we calculate by the formula: a = (V – V0) / t.
Let’s make a calculation: a = (60 – 40) / 6 = 3.33 m / s2.
Answer: The race car in question is moving with an acceleration of 3.33 m / s2.
