Answer:
A) v = 40 m / s, B) v_average = 20 m / s
Explanation:
For this exercise we will use the kinematics relations
A) the final velocity for t = 5 s and since the body starts from rest its initial velocity is zero
v = vo + a t
v = 0 + 8 5
v = 40 m / s
B) the average velocity can be found with the relation
v_average = vf + vo / 2
v-average = 0+ 40/2
v_average = 20 m / s

A. iodine is located in period 5, group 17 and is classified
as a nonmetal
Group is the column, period is the raw.
Answer:
2440 N
Explanation:
As,F=m*a.....
From the question we have
force = 976 × 2.5
We have the final answer as
2440 N
