Problem
Aleš was procrastinating with his tablet when he realized that he is late for his class. The only way to make it on time was to run without stopping. Therefore he started running uphill with speed v. The road was inclined at an angle α. After a while (at time T) he realized that he still carries a brick that he meant to leave in his tent. He is able to throw the brick only with an initial speed w. Determine the angle at which Aleš should throw the brick in order to hit his friend that is sitting in the same spot he was sitting. Is it possible that Aleš will not be able to do this? You should not account for any reaction time.
