Hi Every1
Got question on vectors which i cant handle, can some please show me how to go through this, thankyou!
A body has initial velocity u ms-1 and accelerates uniformly at a ms-2 for t
seconds, reaching a velocity of v ms-1.
The relationship between these measures is:
v = u + at.
Its displacement, s metres, over this period is given by:
s = ut + 0.5at^2
1. A body is initially at rest and accelerates for 8 secs at
5
-1 ms-2
2
a) what is its final velocity and b) what is its displacement
I've worked out the final velocity to be
40
-8
16
How do you work out displacement??
