hey,
a cambridge q
a particle p1 is rpojected from the origin with velocity v at an angle of elevation @
the max height is v^2sin^2@/2g
a second particle p2 is projected from the origin with velocity 0.75v at an angle of 0.5@ to the horizontal
the 2 particles reach the same max height
show that cos@ =1/8
do the 2 particles take the same time to reach this max height? justify
