Question

Problem 4: A rock is fired at ground level with an initial speed of 42 m/s, at an angle of 31° above the horizontal. It hits a target above the ground 2.2 seconds later. (a) What is the horizontal distance, in meters, from where the rock was fired to where it hits the target? (b) What is the vertical distance, in meters, from where the rock was fired to where it hits the target?
