B) A 1300 -kg car is pushing an out-of-gear2200 -kgtruck that has a dead battery. When the driver steps on theaccelerator, the drive wheels of the car push horizontally againstthe ground with a force of 4500 N . The rolling friction of the carcan be neglected, but the heavier truck has a rolling friction of760 N , including the \"friction\" of turning the truck's drivetrain.What is the acceleration aT of the truck?
C) An 89.0 kg spacewalking astronaut pushes offa 620 kg satellite, exerting a 85.0 N force for the 0.540 s ittakes him to straighten his arms. How far apart are theastronaut and the satellite after 1.50 min?
