Use the values from practice it to you work this exercise. suppose the same two vehicles are both traveling eastward, the compact car leading the pickup truck. the driver of the compact car slams on the brakes suddenly, slowing the vehicle to 5.79 m/s. if the pickup truck traveling at 18.5 m/s crashes into the compact car, find the following.
a. the speed of the system right after the collision, assuming the two vehicles become entangled
b. the change in velocity for both vehicles
c. the change in kinetic energy of the system, from the instant before impact (when the compact car is traveling at 5.79 m/s) to the instant right after the collision
the masses are, pickup truck mass of 1.73 multiply. gif 103 kg and compact car mass of 9.32 multiply. gif 102 kg

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
