Where on Earth​ might you find these conditions?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

How is zig zagging a form of acceleration?
