Yes I can see now why the way I typed the equation is wrong. It's given as v = w x r in the question. The separate work done question is written as "Work done = force x distance (f.d)". Is this the key distinction?
Therefore am I right in thinking that I should use dot product to calculate a...
The tangential velocity of a body rotating about the centre point "O" is given by v=w.r, where w is angular velocity and r = radius. give that the vectors
w = 3i - 2j + 7k
r = 2i + 5j - 3k
a) Calculate the magnitude of velocity
b) the vector product in the form i+j+k
So far I have the vector...
