1. You are standing on the edge of a roof of a building that is 25 m high. You threw ball at an angle of 70 degrees with respect to horizontal with a speed of 2 m/s. a) Find the velocity vector of the ball after 1 second. b) What is the direction of motion after 1 second? c) What was the time of flight? d) How far from the building in the x-direction did the ball land on the ground? 2. You are standing on the edge of a roof of a building. You threw the ball at an angle of 70 degrees with respect to horizonal. After 2 seconds, the ball hits the ground 3 m away from the building.
