Rosetta wants to write equations in the form y = mx + b for the lines passing through point P that are parallel and perpendicular to line g
First
she finds the slopes of these two lines. What could she do next to find the
y-intercepts? Please help

im guessing the west of station b

i think it would be 5

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
