Question

On a velocity-time graph of a person's walk, if a person is slowing down in the positive direction, then acceleration is in the negative direction.For example, the positive direction is [E]. If a person's acceleration is -1m/s^2, then it is 1 m/s^2 [West]. But that doesn't make sense, since the person is still walking east, but slowing down.

Answer 1

To slow down a person moving East, you push West.

F = m A

Answer 2

Thanks!
