2.Inelastic Collision. Two automobiles of 540 and 1400 kg collide head-on while
moving at 80 km/h in opposite directions. After the collision the automobiles remain locked together.
(a)Find the velocity of the wreck immediately after the collision.
(b)Find the kinetic energy of the two-automobile system before and after the collision.
(c)The front end of each automobile crumples by 0.60 m during the collision. Find the acceleration (relative to the ground) of the passenger compartment of each automobile;
make the assumption that these accelerations are constant during the collision.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
