Question

Can some answer 7 a and b please

Answer 1

Answer:

a) v = 1.7 m/s

b) s = 18.75 m

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
