- (III) A fugitive tries to hop on a freight train traveling at a constant speed of 5.00 m/s Just as an empty box car passes him, the fugitive starts from rest and accelerates at a= 1.4 m/s2 to his maximum speed of 6.0 m/s which he then maintains. (a) How long does it take him to catch up to the empty box car? (b) What is the distance traveled to reach the box car?arrow_forward(II) Roger sees water balloons fall past his window. He notices that each balloon strikes the sidewalk 0.83 s after passing his window. Roger’s room is on the third floor, 15 m above the sidewalk. (a) How fast are the balloons traveling when they pass Roger’s window? (b) Assuming the balloons are being released from rest, from what floor are they being released? Each floor of the dorm is 5.0 m high.arrow_forward(III) An unmarked police car traveling a constant 95km/h is passed by a speeder traveling 135km/h Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car’s acceleration is 2.60m/s2 how much time passes before the police car overtakes thespeeder (assumed moving at constant speed)?arrow_forward
