Velocity is a vector so it can have a magnitude and direction.
B. 34 m/min east
^magnitude ^direction
hope this helps :)
Answer: Its the last one: The position of the block will change
Explanation: Since the forces are unbalanced, one side of the block will be stronger, therefore making the block move.
Answer:
hmm let's see
Explanation:
ok, ill use the second equation of motion, u see its quite simple
recall that
average velocity= u+v/2
now think of that v like a box you can can call it velocity lol obviously its velocity
now remember the first equation of motion which is
v=u+at now this is inside the box, now you have to replace the v with it
then it becomes u+u+at/2
now u notice there are two initial velocity u know what to do with that
now it becomes
2u + at/2 now since the numerator applies to both then you can simplify it like this
2u/2+at/2
all the same the pont im trying to make is that you can use imaginative ways to mater derivation you can also reverse it if you don't unferstand you can drop your number
