How To Draw Car Sketches
Physics! Plzz Help?
A car traveling at a speed of unifrom of 20 m / s for 5 seconds. the brakes are then apploied and the car stops even late in a more 8s. Draw a sketch graph of velocity against time. To what extent the car after traveling the brakes are applied?
We will resolve first the issue analytic initial velocity = u = 20m / s Final velocity = v = 0 = Delay time = a = 8s? v = u 0 = 20 m / s – a * 8-20m / s =- 8a or = 20 / 8 = 2.5 m / s ^ 2 Now use the kinematic equation V ^ 2 – u ^ 2 = 2as where s 0 is the distance traveled – (20m / s) = -2 * 2.5 * ss = 20 / 5 = 4 m | 20 m / s | 15 m | / s | | 10m / s | | 5 m / s | 0 2m 4m 6m |___________________________________________ Draw a Distance line connecting 20m / s up to 4m this is his sketch
