Problem Solving Read and analyze each problem carefully. Show your COMPLETE solutions in solving the problems. Final answer must have two decimal places and round off. 1. A ball is kicked horizontally at 8.0 m/s from a cliff 80 m high. How far from the base of the cliff will the ball strike the ground? 2. A golf ball is hit giving it a velocity of 60 m/s at an angle 𝟑𝟓𝟎 with the horizontal. Find the vertical and horizontal component of its initial velocity, time of flight, horizontal and vertical distance of the golf ball.
