9. An object is fired vertically upwards from the ground at time t = 0 s in still air at a speed of 9.6 m/s. On the way up, what is the height of the object above the ground when it has a speed of 1.9 m/s. At what time does it reach this height on the way down? Give both answers separated by a comma to one decimal place.

Possible solution:

use this formula to calculate the required height: „v^2 = u^2 + 2as“ -> 4.513m
use same formula again to calculate the maximum height the object reaches -> 4.697m
then use this formula to calculate the time the object takes to reach maximum: „v=u + at“ -> 0.785s
calculate the time taken for the object to fall from the maximum height to 4.5m (first answer): „s =1/2at^2“-> 0.194s
add together the two calculated times -> 1.0s
