Power in physics is work done over time. So the answer is Power is the rate at which work is done.
Answer:
10
Explanation:
(r) = <10 cos 6t, 10 Sin 6t>
The distance traveled by the object is the magnitude of vector r.
The magnitude of vector r is given by


r = 10
The ball rolled a distance of
d = 12m + 20m.
But the change of position is
x = + 12m - 20m
