A convenient way to show how a fixed quantity is broken down into parts is by using a circle graph.
A circle graph shows different fixed parts in relation to the whole. All of the parts make up the whole.
Answer:
a) 
b) a= 1.79 m/s²
θ = 41.98⁰
Explanation:
arc radius = 12 m
constant speed = 4.00 m/s
(a) centripetal acceleration


= 1.33 m/s²
(b) now we have given

now,


a= 1.79 m/s²
direction


θ = 41.98⁰
I believe that you would weigh around 68 or 69 N, or 7 kilograms.
