What is the magnitude of a vector if the x component is - 12 m and the y component is 21m? 290m

17m

24m

580m

v = 24 m

Explanation:

Given that,

The x component of the vector = 12 m

The y component of the vector = 21 m

We need to find the magnitude of a vector. It can be solved as follows :

or

v = 24 m

So, the magnitude of the vector is equal to 24 m.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
