Question

An object starts from rest and has an acceleration of 2.0 ms−2. What is the speed (v = at) of the object after 7.00 seconds with the correct number of significant digits?

Answer 1

14 m/s

Step-by-step explanation:

Correct number of sig dig will be two since accel has only two SD ( you can only have as many SD as the factor with the LEAST SD)

v = at

= 2 m/s^2 * 7 s = 14 m/s
