A launcher is used to launch a dart with initial speed u from a table at an angle, as shown above. The dart exits the end of the launcher at a heighth above the floor and lands a horizontal distance D from the end of the launcher. A close-up view is included that shows the dart in the launcher immediately before being launched. Inside the launcher. the dart rests on a platform with negligible friction and a compressed spring is released to push the dart out of the launcher Assume air resistance is negligible. a) A student creates an incorrect diagram shown above of the forces exerted on the dart at an instant in time after it has been launched but before it reaches the floor. Indicate what aspect of the diagram is incorrect. Assume air resistance is negligible.
