QAIPMT-2003-Ph-2737: NEET 2003 Physics - Class 11 AIPMT-2003-Ph-2737 Solution: A man throws balls with the same speed vertically upwards one…
A man throws balls with the same speed vertically upwards one after the other at an interval of 2 seconds. What should be the speed of the throw so that more than two balls are in the sky at any time? (Given g = 9.8 )
Multiple Choice Options
- A more than 19.6 m/s
- B at least 9.8 m/s
- C any speed less than 19.6 m/s
- D only with speed 19.6 m/s.
Step-by-Step Verified Solution
When more than two balls means minimum three balls are in the sky then time of flight for the first ball should be more than 4 s.
T > 4 s
2 u g > 4
_ u > 19.6 m/s
