[SOLVED] vector notation and force and force Help- test this morning..
A time dependent force F(t)= 20t N/s acts along the possitive y-axis on a 4.00kg object. The object starts at the origin with the initial velocity
[tex]\vec{}v(0)= (1.00m/s)) \hat{}i-(1.00m/s) \hat{}j[/tex].
a) find the velocity of the object as a function of time.
b) find the position of the object as a function of time
c) what is the speed of the object at time t?
?? the ones given?
I have no idea where to start..it seems simple enough..
can someone please please please help me out?
by this morning to be exact..(I have a test)
