A 2.0kg object initially at rest at the origin is subjected to a time-varied force. What is the objects velocity at 4 seconds?
The Graph
For the first two seconds there is a force of 6.0N. The the force decreases linearaly to 0N at 4 seconds. How do I find the velocity of the object at 4.0 seconds?
I got the velocity at 2 seconds by using F=ma and solving for a:
6.0=2.0a
a=3
With that acceleration I then found:
V=Vi+at
V=0+(3)(2)
V=6
I just don't know how to get the rest.
