Question

plz help fasst i will mark u brillient

Answer 1

maximum height in a projectile is given by : u^2sin^2(theta)/2g, since u is taken constant(given) when the angle is increased sin(theta) will increase as well(as sin function increases for increase in angles).
hence, maximum height changes from u^2/8g to u^2 (3)/4g that is, height is comparatively increased.
