A ball is dropped from rest from a height of 1 min a frictionless tube as shown in the figure. If the tube profile is approximated by two straight lines (ignoring the curved portion), the total distance travelled (in m) by the ball is (correct to two decimal places).

- 2.414 m
- 1.414 m
- 3.414 m
- 5.414 m
Correct Option: A
| = sin 45° | AB |
| AB = | = | = 1.414m | sin 45° | sin 45° |
Total travel, OA + AB = 1+1.414 = 2.414 m
