The equations of motion for the horizontal and vertical directions are reduced to the following for a projectile launched horizontally, Le. '00,, = 0m/ S: Here, y is taken to be positive in the vertical direction, and g = 9.8 m/s. Part A Rearrange the eqution for horizontal position, x, to make t the subject. Express your answer algebraically. VO AEQ t= Submit Request AnswerV PartB Substitute this expression for t into the equation for y, thus finding an expression for the vertical position, y, in terms of 3:. 1mm and g. Illequest Answer V PartC For a projectile launched horizontally, we can see that m2 = kg, where wand yare the instantaneous positions of the projectile in the horizontal and vertical directions respectively and k is the proportionality constant. Find the expression for k in terms of van: and g. Quest
