A boy is standing on a long railroad car throws a ball straight upwards.The car is moving on a horizontal road with an accelaration of 1m/s^2. and the projection velocity is 9.8m/s.How far behind the boy will the ball fall on the car.
Not entirely sure what to use but i tried using the basic equations of motions and relative velocity but without an actual velocity for the rail car i found it really hard
The Attempt at a Solution
I fist used the basic V=U+at and found the time taken to go up.
Hence time taken to come down will be 2t.In this same the car should have travelled a certain distance.Now this is where im stuck since i only have the acceleration not the speed of the car D:
I juggled around but couldnt get the proper answer which was 2 meters
Any help would be much appreciated!
