A runner starts from rest and achieves a maximum speed of 8.85 m/s. If her acceleration is 9.67 m/s2, how long does it take her to reach that speed?

The appropriate answer is "0.9152 seconds".

Explanation:

The given values are:

Maximum speed,

v = 8.85 m/s

Acceleration,

u = 9.67 m/s²

Now,

⇒

By putting the values, we get

⇒

⇒      

⇒            

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

total distance/total time

(85 + 82)/(5+3)

167/8

20 just over
