Homework Statement
What relationship exists between the velocity and acceleration vectors? Prove your claim
Homework Equations
Since speed = |v| = constant, acceleration_tangential = d|v|/dt = 0. My question is on the "prove your claim part" Can I see simply just say let v(t) = a*i + b*t j (i = unit vector i, j = unit vector j). And since there is no t next to a or b, v(t) doesn't change and it's deritvative is zero ? Or do I have to show using dot product/cross product
