Question
HLPaper 1A
An object is thrown from a cliff at an angle to the horizontal. The ground below the cliff is horizontal.
Three quantities are known about this motion.
I. The horizontal component of the initial velocity of the object
II. The initial angle between the velocity of the object and the horizontal
III. The height of the cliff
What are the quantities that must be known in order to determine the horizontal distance from the point of projection to the point at which the object hits the ground?
