Question

It takes Harry 40s to walk from x1 = -12m to x2 = -46m . What is his velocity?

Answer 1

it would negative and is would be 38/40 m/sec

Answer 2

His velocity is -0.85m/s

Step-by-step explanation:

Velocity is defined as the change in position divided by the time required for that change:

`V=(x_(2)-x_(1))/(t)`

In this case:

`V=(-46m-(-12m))/(40s)=-0.85m/s`
