15. The direction of acceleration is determined by the change in velocity (Av = vr - v3. Complete the following table, then below the table invent a situation where these velocities might happen. "A" is done for you. Av a (pos or neg) A 0 10 m/s B 0 -10 m/s C -2 m/s -5 m/s D -2 m/s 2 m/s E 5 m/s 0 A. of pedos at a dtae-light prodded the gas and goes from will (Oja) to 10ula B. C. D. E. 16. Explain why the following misconceptions are false. a) If acceleration is zero, the object must be standing still. b) Velocity and acceleration are always the same sign (both positive or both negative). c) If speed is increasing, acceleration must be positive
