C)greater than 10 units.

Question

Quizplus · Accepted Answer

The vertical component of a vector at an angle is given by the magnitude of the vector multiplied by the sine of the angle. In this case, the vertical component is 10*sin(60°) = 8.66 units, which is less than the magnitude of the vector (10 units). Therefore, the correct choice is A.
