An athelete jumps at an angle of30^@ with a maximum speed of9.4 m//s.

1.	An athelete jumps at an angle of30^@ with a maximum speed of9.4 m//s. Find the range covered by him in the above jump. Suggest the angle by which
Answer» SOLUTION :`R=(mu^2sin2theta)/G=((9.4)^2sin60^@)/(9.8)=7.8m` RANGE will be MAXIMUM when `theta=45^@`
