holder på med ett fysikk oppg sett og skjønner ikke hvordan toget og bilen beveger seg. prøvd å tegne opp men gir ingen mening.
**2.42 A train has a length of 92 m and starts from rest with a constant
acceleration at time t = 0 s. At this instant, a car just reaches the end of the train.
The car is moving with a constant velocity. At a time t = 14 s, the car just reaches
the front of the train. Ultimately, however, the train pulls ahead of the car, and at
time t 28 s, the car is again at the rear of the train. Find the magnitudes of (a)
the car’s velocity and (b) the train’s acceleration.
