The car increased its speed in 10 seconds from 18 to 27 km / h. Determine the projection of the car’s acceleration during this time.
Task data: t (acceleration duration) = 10 s; V0 (initial speed) = 18 km / h (5 m / s); V (final speed) = 27 km / h (7.5 m / s).
The acceleration projection of the vehicle under consideration can be determined by the formula: a = (V – V0) / t.
Calculation: a = (7.5 – 5) / 10 = 0.25 m / s2.
Answer: The projection of the acceleration of the vehicle in question is 0.25 m / s2.
