Question

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

Answer 1

\[formula: a=\frac{ v _{f}-v _{i} }{ t }\]

Answer 2

A = Final Velocity-initial velocity

Answer 3

You can get the acceleration by substituting the initial velocity and the velocity he achieved. To work out the distance, you can use\[x=v _{0}t+\frac{ 1 }{2 }a t^{2}\]

Answer 4

@ChristineToTheRescue do you understand this, or should I try to explain more?

Answer 5

@Peter14 somewhat...

Answer 6

Could you explain a teensy bit more?

Answer 7

explain what specifically?
