Procedure:
  1. Draw a straight line on the ground with a marker or a chalk.
  2. Ask one of your friends to stand \(1\) to \(2\ m\) away from it.
  3. Let your friend gently roll a ball along the ground in a direction perpendicular to the line.
  4. Note the time at the moment the ball crosses the line and also when it comes to rest.
  5. Measure the distance between the point at which the ball crosses the line and the point where it comes to rest.
  6. You can use a scale or a measuring tape.
  7. Let different groups repeat the activity.
  8. Record the measurements in the given table format.
  9. In each case, calculate the speed of the ball.
