Distance between a frog and an insect on a horizontal plane is 9 m. Frog can jump with a maximum speed of √10 m/s . Minimum number of jumps required by the frog to catch the insect is (Take g=10 m/s2)
9
Range is maximum for 45∘ projection
The distance covered in one hop will be, R = u2g=1 m
Hence, it would take 9 jumps
