Homework Statement
A robot working in a nuclear power plant moves along a straight track. If it experiences a force
F(t) = -Fi [ 1 + (4.0t - 2.0T)/T ]
where T is a constant with the units of time, what is the instantaneous speed of the robot at the very end of the interval 0 [tex]\leq[/tex] t [tex]\leq[/tex] T. It was at rest at t= 0
Relevant equations
ma = -Fi [ 1 + (4.0t - 2.0T)/T ]
[tex]\int[/tex] a(t) = v(t)
How do I integrate that?? it will be a = [ -Fi [ 1 + (4.0t - 2.0T)/T ] ] / m
but how do I integrate with so many variables... do I plug in t for T? No mass given...
