Question

A particle moving uniformly along the x axis is located at 13.4 m at 1.72 s and at 3.13 m at 4.6 s. what is its average velocity during this time interval? answer in units of m/s.

Answer 1

The formula for average velocity is: (final distance - initial distance9 / (final time - inital time). Using that, the anwer will be:

(3.13 - 13.4)m / (4.6 - 1.72)s = - 3.57 m/s.

According to these results, if we assume positive numbers are right, the particle was moving left.
