Question

What is the acceleration of the cyclist from 175 to 200 seconds? A. -12 m/s2 B. 0m/s2 C. 12 m/s2 D. Can't be determined

Answer 1

The correct answer is D

Step-by-step explanation:

The expression for the accelerated ion is

a =
`(v_f - v_o)/( \Delta t)`

therefore to find the variation of time is needed, which is a data given in the problem.

It also needs to be emptied of speed, which is not given.

Consequently we cannot find the acceleration in this exercise.

The correct answer is D
