A ball is released from a height of 1 m on a smooth hemispherical surface as shown. Find its velocity when it is at a height of 0.5 m. (Take g = 10 m/s²).
Multiple Choice Options
- A 20 m/s
- B 10 m/s
- C √10 m/s
- D 5 m/s
Step-by-Step Verified Solution
mg(1) = (1/2)mv² + mg(0.5) => v² = 10 => v = √10 m/s
