An object moves on a trajectory given by bold r left parenthesis t right parenthesis equals left angle 10 cosine 6 t comma 10 sine 6 t right angle for 0 less than or equals t less than or equals pi. how far does it travel?

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        

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
