separate your x and y components
x:
v0x=170cos30
x=?
t= from y
y:
v0y =170sin30
a =-9.81m/s^2
y = -1750m
t =
solve for t using y=v0*t+(1/2)at^2
then plug t into your x component to get x
(make sure to keep your initial y velocity positive and your acceleration and y distance negative)
Homework Statement
A rectangular box at rest in S' has sides a'=2m, b'=2m, c'=4m. The side c' is parallel to z' axis of S'; the side b' forms an angle 45deg with x' axis of S'. S' moves with v=0.5c with respec to S, along its x axis. Find the volume of the box in S and S'.
