KE = ½mv² = ½(4.00 kg)(16.0 m/s)² = 512 J
How do you find instantaneous velocity
Select a point on a distance-time curve graph. Draw a tangent to the curve at that point. Tangent -> hypotenuse of right angled triangle. Opp/adjacent in graph units is vel at that point -> in distance and/or time
Answer:
Car A would have a better average speed
