a student throw soft ball out of the window at different angle to the horizontal all softballs have the same initial speed V is equal to 10 under root 3 metre per second it turns out that all softballs landing velocity make angle 30 degree operator with the horizontal find the height H in metre of the window above the ground |

Answer» All soft balls have the same INITIAL speed V = 10sqrt3 MS^(-1). It turns out that all soft balls landing VELOCITIES make angles 30^@ or GREATER with the horizontal. Find the height h (in m) of the window above the ground. Minimum θ implies minimum Vfy and maximum Vfx. |
