A roller coaster climbs a hill, then travels down the other side and up another hill. Where is the greatest?

a. At the top of the first hill

B)Halfway up the hill

c. At the bottom of the hill

d. At the top of the second hill

m = 350kg
angle = 50 degrees
initial velocity = 150 m/s
Find following:
a) what is velocity after 10 seconds.
b). what is direction of velocity at 10 seconds
c). what is position of rocket at 10 seconds

accleration in x direction is given by = 14.29 * cos (theta) -0.0001286*(v^2)*cos(theta)
accleration in y direction is given by = 14.29 * sin(theta) -0.0001286*(v^2)*sin(theta) - g

You may have to integrate or take derivatives to get theanswer.

Please help urgently!!!!
