ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements. In working this problem, assume the value of "g" to be 9. 8 m/s2 with two (2) significant digits unless otherwise stated.

A force of 80 N is exerted on an object on a frictionless surface for a distance of 4. 0 meters. If the object has a mass of 10 kg, calculate its velocity.
