What is the acceleration of a cyclist if his speed changed from 7 to 2 m / s in 5 seconds?
| June 16, 2021 | education
Task data: t (duration of movement of a given cyclist) = 5 s; V0 (initial speed) = 7 m / s; V (speed after acceleration) = 2 m / s.
The acceleration of a given cyclist is calculated by the formula: a = ΔV / t = (V – V0) / t.
Let’s perform the calculation: a = (2 – 7) / 5 -5 / 5 = -1m / s2.
Answer: The assigned cyclist was moving with an acceleration of -1m / s2.
