Problem: The figure(Figure 1) shows the velocity graph of a 2.7kg object as it moves along the x-axis.What is the net force acting on this object A. At t= 1 s?B) At 4 s?C) At 7 s?

FREE Expert Solution

Acceleration of the object is expressed as:

a=vxt

Newton's second law:

ΣF=ma, where F is the net force, m is the mass, and a is the acceleration of the object.
