Pls help ......... ​

I assume, like you said, you know this and need time help so less explaining:

||F ||= √fx^2+fy^2

||F|| = 78.23682

Angle = tan-1(64/45)

Angle = 54.9

Second:

||f||| = √22^2+6^2

||f|| = 22.8

Angle = tan-1(6/22)

Angle = 15.26

v = 1.26 m/s

Explanation:

Given that,

The radius of the circle, r = 20 cm = 0.2 m

The centripetal acceleration of the object, a = 8 m/s²

We need to find the tangential velocity of the object. We know that the formula for the centripetal acceleration is given by :

So, the tangential velocity of the object will be 1.26 m/s.
