Question

observer in an inertial reference frame S sits at rest on the ground and watches a 2050 kg truck meving at a speed of 16 my's to the rightrelative to the ground) colide with a 1395 kg car sitting at rest at a stop ผ9 After the eemson, the truck and the car stick together and move at the sarme final volocty since the Law of Conervaton of Linear Mon entumis known tobe vaid n refere en freme S " ye vented n Phn201 lab), use this law to calculabe the final velocity of the truck/car mass (stuck together after the collision). Indicate a velochy to the right by a positive number and a veloity to the left by a negadive number Submit Anewer Tries 0/3 Suppose that second observer r es along in a reference rame S Ike another car traveling st 19 m/s n the same directin as the trick and i ato es the colls on occur. what il he see? use the Gal ean Vel cty Transformation (Classical Relativity) to caloulate what he would measure for the velocity of the truck before the collision, the velocity of the car before the colisian, and the welocity of the truckjcar (shuck together after the collision Velscity of the Truck Before the Colision Velecity of the Car Before the Collision Velocity of the Truck/Car After the Collision sont Answer j Tries D/3 According to the Principle of Newtonian Relativity, all of the lews ef mechanics should have the same form in all inertial reference frames. For instance, this means that the Law of Conservation of Unear Momertum should work for the observer i, S and for the ebserve n S despite the fact that they measure emeent values tor the vele tes e, the 00 ets Lers chea th·Use the elootes the yo, determ neano the Ob ver n 5' and caleu ste the total mamentum that the oboerver in S ses both before and after the colision. Within round-aff error did you get the same value for the total mementum both before and after the collsion?(You shauld) Ester the value of the total momentum measured by the ebserver in Suomt Answe Tries oys Send Feedbeck This discussion is closed
