horizontal velocity=15cos25
vertical initial velocity= 15sin25
in the vertical:
hf=hi+viv^t-4.9t^2
0=1.5+15sin25*5-4.9t^2
solve the quadratic equation.
an object is thrown from 1.5m above the ground with a velocity of 15m/s and at an angle of 25deg with the ground. using vectors and motion equations, determine how long the object will remain in the air before returning to the ground. ARGHHHHHH help please..
