Hello, there are several variables I have had to find for this problem but I am stuck on figuring out the last two. Please help! Thank you.

A rock is thrown off a cliff at an angle of 60∘ with respect to the horizontal. The cliff is 128 m high. The initial speed of the rock is 32 m/s.

Known:
v0= 32 m/s

v0x= 16 m/s

v0y= 27.6 m/s

Δy= 39.12 m

t(ground)= 8.76 s

Δx(total)= 138.72 m

 

Unknown:

How far has it moved horizontally when it is at maximum altitude?

Δx= ?

What are the horizontal and vertical positions of the rock relative to the edge of the cliff at t = 4.4 s. Assume that the origin (0,0) for this part is loacted at the edge of the cliff. Enter the positions with their correct signs.

Position: (x= ? , y= ?)m
