3.0 A i got it off Quizlet and there usually always right lol can't submit tho my answers to short.... Dot dot dot
Scientist would check what other scientists have said before they come up with their own scientific question. That way they can record the results from the others and compare them with their own findings when they conduct their own experiments and record the findings.
In projectile motion horizontal motion has zero acceleration and when there is no air resistance acting on the object the motion will be uniform. Motion in the vertical direction is accelerated downwards to to the acceleration due to gravity
Answer:
Explanation:
The horizontal distance traveled by the projectile is given by the formula
The formula for the time of flight is given by
Case I: when the launch angle is 30°
So, 
Horizontal velocity = u Cos 30 = 0.866 u
Case II: when the launch angle is 60°
Horizontal velocity = u Cos 60 = 0.5 u
By observing the case I and case II, we conclude that
R1 = R2
Horizontal velocity 1 > Horizontal velocity 2
T1 < T2
