Subject: pls answer-a particle is projected at an angle of 60 degree with the horizontal with a speed
let required time be t sec.
speed in horizontal direction(v1)=20m/s.
speed in vertical direction(v2)= gt =10t
total speed=root(v1*v1 + v2*v2)
total speed= v1 / 2 = 20/2=10m/s
10=root(400+100*t*t)
hence t=root(3)sec
