With what acceleration should a car moving at a speed of 36 km / h brake to stop in 10 seconds?
| August 6, 2021 | education
These tasks: V0 (the speed of the vehicle under consideration before the start of braking) = 36 km / h (in SI V0 = 10 m / s); t (deceleration time required) = 10 s.
The acceleration with which the vehicle in question should brake is calculated by the formula: a = (V – V0) / t = -V0 / t.
Let’s perform the calculation: a = -10 / 10 = -1 m / s2.
Answer: The constant acceleration of the vehicle in question should be -1 m / s2.
