Answer:

a) v = 1.7 m/s

b) s = 18.75 m

Step-by-step explanation:

Given,

a)

The initial velocity of Mr. Comer, u = 0.8 m/s

The acceleration of Mr. Comer, a = 0.06 m/s²

The duration of his travel, t = 15 s

Using the first equation of motion,

v = u + at

= 0.8 + 0.06 (15)

= 1.7 m/s

Hence the final velocity of Mr.Comer, v = 1.7 m/s

b)

Using the second equations of motion

s = ut + 1/2 at²

= 0.8 (150 + 0.5 x 0.06 (15)²

= 18.75 m

Hence, the distance traveled by Mr. Comer, s = 18.75 m
