Question

8. In a competition a sprinter starts from rest and achieves a velocity of 30 m/s in a time of
6s. What is his average acceleration?
a.
10 m/s2
b. 8 m/s2
c. 7 m/s2
d. 5 m/s2​

Answer 1

Answer:

Option:- d. 5 m/s²

Explanation:

Given,

u(Initial velocity) = 0 m/s

v(Final velocity) = 30 m/s

t(Time) = 6s

Average acceleration = (v-u)/t

= (30-0)/6

= 30/6

= 5 m/s²

Therefore, 5 m/s² is the average acceleration.
