Answer:
y = 28 m
Explanation:
To answer this question, we will use Pythagorean theorem.
This is because the givens along with the requirement form a right-angled triangle.
the x-component is one of the sides = 21 m
the required y-component is the other side
the magnitude is the hypotenuse = 35 m
Applying Pythagorean theorem, we will be able to get the value of the y-component as follows:
(magnitude)^2 = (x)^2 + (y)^2
(35)^2 = (21)^2 + (y)^2
(y)^2 = 784
y = 28 m
Hope this helps :)
