can someone help me with this problem i am very new to this and i am having trouble answering it

Which concept most relates to this question?

a) linear motion

b) free fall

c) length

d) instantaneous velocity

e) non-linear acceleration

Which equation is best suited to solve this problem:

a) v^2=v(average)^2+2ax

b) F=mv(average)

c) v(average)*t = x

d) v(average)=x(t)

e) x=v(average)+(a/2)t^2

The coordinate of an object is given as a function of time by a (t) = 50t + 1.5t , where x is in meters and t is in seconds. What is the average velocity over the interval from t = 0 8 to t = 6 8?
