Question

Distance between a frog and an insect on a horizontal plane is 10m. frog can jump with a maximum speed of root 10 m/s. g=10m/sec^2.mwximum number of jumps required by the frog to catch the insect is

Answer 1

Number of jumps =10.

Here it may be noted that to calculate firstly the number of jumps we have to be clear that for minimum number of jumps, range has to be maximum.

Here to calculate the number of jumps, firstly,

the maximum range u2g=(10−−√)210u2g=(10)210=1m=1m .

Total distance =10m 10m.

Thus the  number of jumps =1
