- Check Your Understanding A cave diver enters a tong underwater tunnel. When her displacement with respect to the entry point is 20 m, she accidentally drops her camera, but she doesn’t notice it missing until she is some 6 m farther into the tunnel. She swims back 10 m but cannot find the camera, so she decides to end the dive. How far from the entry point Is she? Taking the positive direction out of the tunnel, what is her displacement vector relative to the entry point?Please write legibly.
