Question

James accelerated from rest at a rate of 8 m/s² for 14 seconds. What was his finalspeed?

Answer 1

Given

The acceleration,

`a=8\text{ m/s}^2`

The time,

`t=14\text{ sec}`

To find

The final speed

Step-by-step explanation

Let the final speed be v.

Thus,

`\begin{gathered} a=(v)/(t) \\ \Rightarrow8=(v)/(14) \\ \Rightarrow v=112\text{ m/s} \end{gathered}`

Conclusion

The velocity is 112 m/s.
