Question
1.An automobile of mass 1500 kg moving at 25.0 m/s collideswith a truck of mass 4500kg at rest. the bumpers of the twovehicles lock together during the crash. a. Compare the force exerted by the car on the truck with thatexerted by the truck on the car during the collision.Is one forcelarger than the other or are they equal in magnitude to eachother? b. What is the final velocity of the car and the truck justafter the collision? show your calculations. 2. the same collision on the top uestion takes place, onlythis time the car and the truck bounce off each other completlyelastically. c. Compare the force exerted by the car on the truck with thatexerted by the truck on the car during the collision . is one forcelarger than the other or are they equal in magnitude o eachother? d. what are the final velocities of the car and the truck justafter the collision ? show calculation thanks 1.An automobile of mass 1500 kg moving at 25.0 m/s collideswith a truck of mass 4500kg at rest. the bumpers of the twovehicles lock together during the crash. a.

1.An automobile of mass 1500 kg moving at 25.0 m/s collideswith a truck of mass 4500kg at rest. the bumpers of the twovehicles lock together during the crash. a. Compare the force exerted by the car on the truck with thatexerted by the truck on the car during the collision.Is one forcelarger than the other or are they equal in magnitude to eachother?the force exerted by the car on the truck and the forceexerted by the truck on the car during the collision.
will form action reaction pair
they are equal in magnitude and opposite in direction according tonewtons third law
b. What is the final velocity of the car and the truck justafter the collision? show your calculations.
v=m1u1+m2u2/m1+m2=1500*25+0/1500+4500=6.25m/sec
2. the same collision on the top question takes place, onlythis time the car and the truck bounce off each other completlyelastically.
c. Compare the force exerted by the car on the truck with thatexerted by the truck on the car during the collision . is one forcelarger than the other or are they equal in magnitude o eachother?
the force exerted by the car on the truck and the forceexerted by the truck on the car during the collision.
will form action reaction pair
they are equal in magnitude and opposite in direction according tonewtons third law
d. what are the final velocities of the car and the truck justafter the collision ? show calculation
v1=[m1-m2/m1+m2]u1+[2m2/m1+m2]u2=[1500-4500/6000]*25+[9000/6000]*0=-12.5m/sec
as negative sign indicates the automobile moves back with thevelocity 12.5m/sec backwards
v2=[m2-m1/m1+m2]u2+[2m1/m1+m2]u1=[4500-1500/6000]*0+[3000/6000]25=12.5m/sec
moves in initial direction of the automobile
