2b is true minimum kinetic energy

sonam1010: thanks but how???

Abh1shek: Answer 29.) Since We Know That The Projectile Can have same range For Two Different Angles (θ and 90-θ),So according to given Question R=5√3m

sonam1010: yes

Abh1shek: Answer 29.) Since We Know That The Projectile Can have same range For Two Different Angles (θ and 90-θ),So according to given Question R=5√3m ,On Calculating Range We get θ=30 and therefore , 90-θ=60 Putting these Two Values In Time Period Formulae We Get T1=1s And T2=√3 ,so Projectile Can Strike Between (√3-1)sec
