question 2 - if juan starts out at 10m/s, and in 15 s speeds up to 60 m/s, what is his acceleration?

a - 10 m/s^2

b - 3.33 m/s^2

c - 4 m/s^2

d - 15 m/s^2

B) 3.33 m/s²

Explanation:

Given that,

The initial velocity of Juan, u = 10 m/s

Final velocity of Juan,  v = 60 m/s

Time taken, t = 15 s

The acceleration is given by the relation

                          a = v-u/t  m/s²

Substituting in the above equation

                           a = 60 - 10 / 15

                           a = 3.33 m/s²

Hence, the acceleration of the Juan is, a = 3.33 m/s²

your answer is, orbit around the nucleus
