Spring mounted bumpers ensure that the collision is essentially elastic. If the velocity of the truck is 17 km/h (in the same direction as the car's initial velocity) after the collision, what is the initial speed of the car? A) 25 km/h B) 50 km/h C) 38 km/h D) 13 km/h Title: Re: A car of mass 1028 kg collides head-on with a parked truck of mass 2000 kg. Post by: padre on Jun 11, 2014 Content hidden
