Question

A projectile is launched with an inital velocity of 30.0m/s at an angle of 60 degrees above the horizontal. How far does it travel. Please show me how to solve this.

Answer 1

Draw your triangle
Decide whether to use sin or cos
find value
dh=vht
Solve for dh.

Answer 2

Payday: stop answering if you have no idea.

time in air: hf=hi+30sinTheta*t-1/2 g t^2
hi=hf=0
solve for time in air t.

then, hoizontal distance
distance=timeinair*30cosTheta
