Question

A runner achieves a velocity of 11.1 m/s 9s after he begins. What is his distance

Answer 1

49.5 is the correct answer

Answer 2

49.5 m

Step-by-step explanation:

A runner "achieves" a velocity of 11.1 m/s , t = 9s" after" he begins.

On applying formulas and conditions in this Q, its superb easy.

AFTER SAYS BODY WAS AT REST AS WELL AS ACHIEVE.

• u = 0
• v = 11.1m/s
• t = 9s

a = v-u/t

• a = 11.1-0/9 = 11.1/9

S = ut +1/2at²

• S = 0*t + 1/2 * (11.1/9)*9*9
• S = 1/2* 99.9
• S = 49.5 m
