If so then
melon trajectory
u = 12.1 forever
x = 12.1 t so t = x/12.1
v = g t = 9.81 t
y = 4.9 t^2
so
y = 4.9 x^2/146 = .0335 x^2
y^2 = .00112 x^4
when they hit
14.9 x = .00112 x^4
x^3 = 13303
x = 23.7
y = .0335 x^2 = 18.8
A truck loaded with cannonball watermelons stops suddenly to avoid
running over the edge of a washed-out bridge. The quick stop causes a
number of melons to fly off the truck. One melon rolls over the edge with an
initial speed of vi = 12.1m/s in the horizontal direction. A cross-section of
the bank has the shape of the bottom half of a parabola with its vertex at the
edge of the road, and with the equation y2 = 14.9x, where x and y are measured
in meters. What is the x coordinate of the melon when it splatters on the bank?
Tries 0/10 What is the y coordinate of the melon when it splatters on the bank?
