A teacher's car has run out of gas and he is trying to push his car to the side of the road. The car's mass is 1,300 kg and the teacher is pushing it at an acceleration of 0 08 m/s2 Determine the force the teacher is applying to his car to move it. 104J, 16.250J, 104N, 16,250N

What the heck r u talkin bout? ?

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
