This spreadsheet generates diagonal projection questions. Students are given some quantities and asked to find the others. This helps students develop their problem solving skills whilst they practise solving projectile problems. All of my drills are fully Excel compatible spreadsheets. This one is a question generator, which can be used to generate an unlimited number of unique questions. Just press F9 (PC) or Cmd+= (Mac) to refresh the spreadsheet and generate a new question. Answers are correct to 2sf, so use some discretion when reviewing answers.
