Awoman parked on a slight incline observes that the car beside her starts moving forward at approximately 0.30 m/s. when she looks at the parking meter on her right, she realizes that it is she herself who is moving. how fast is the woman moving with respect to the ground? assume that forward is in the positive direction

0.30 m/s
0.60 m/s
-0.30 m/s
-0.60 m/s

The correct answer is Option -0.30 m/s.

Explanation:

Let the speed in forward direction be positive and the speed in backward direction be negative.

We are given that a woman has parked her car on a slight incline surface and the car beside her was moving with a speed of 0.30m/s in forward direction.

But then she realizes that her car was actually moving in the backward direction and not the car beside her.

Since, the car beside her and the ground are stationary, the magnitude of the relative velocity would remain the same and only the direction changes.

So, her car is moving with the speed of 0.30 m/s in backward direction.

Hence, the correct answer is Option -0.30 m/s.
