Students in lab measure the speed of a steel ball launched horizontally from a table top to be 3.6 m/s. If the table top is 1.0 m above the floor, where should they place a 20 cm tall tin coffee can to catch the ball when it lands?
____m
Steps:
1) Split problem into x and y components, or horizontal and vertical
2) Calculate time using y components
3) Substitute this answer into same equation for x component, solving for d
Final answer: 65.46 cm
Note: This answer assumes that the ball is launched at the very edge of the table and that the ball lands at the very left edge of the can (if the ball is launched to the right)
