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 / s 2 ) Options: A . &nbsp7 B . &nbsp8 C . &nbsp9 D . &nbsp4

Answer: Option C : C Range is maximum for 45 ∘ projection The distance covered in one hop will be, R = u 2 g =1 m Hence, it would take 9 jumps

Question

Distance between a frog and an insect on a horizontal plane is

9 m

. Frog can jump with a maximum speed of

\sqrt{10} m / s

. Minimum number of jumps required by the frog to catch the insect is (Take

g = 10 m / s^{2}

)

Options:

A . 7

B . 8

C . 9

D . 4

Answer: Option C
:
C
Range is maximum for

45^{\circ}

projection
The distance covered in one hop will be, R =

\frac{u^{2}}{g}

=1 m
Hence, it would take 9 jumps
