1) Ms. MacDonald's 1200 kg Hyundai is moving to the right with a speed of 22 m/s. The Hyundai strikes an SUV which is at rest and has a mass of 4200 kg. Their bumpers lock they move off together. a) Draw the before and after picture of the collision (including velocity vectors). There should be two cars in each drawing. minerom Ienri bris lettini snij tol anoitsup9 oi BEFORE SUV AFTER Hvundai V2 22 m/s arli b) Write an equation for the momentum of the system before the collision. pri= mi * VI = 1200 kg * 22 m/s 26,400 kg * m/s c) Write an equation for the momentum of the system after the collision PIr= (m, + m2)v2 = (1200 kg + 4200 kg) v2 EU MODEW S> COT A TE nwab ellor her d) How fast does the Hyundai and SUV move after the collision? 26,400 kg * m/s = (1200 kg + 4200 kg) V2 26,400/5400 = V2 2) Repeat the above steps to but with the truck initially moving 14 m/s to the LEFT. a) DRAW before and after (ans. 4.89 m/s right) b) Momentum equation for before: c) Momentum equation for after: d) Find the velocity of the SUV and car after the collision.
