Homework Statement
A rocket is launched at an angle of 53 degrees above the horizontal with an initial speed of 100 m/s. The rocket moves for 3.00s along its initial line of motion with an acceleration of 30.0 meters per second squared. At this time, its egines fail and the rocket proceeds to move as a projectile.
Homework Equations
1. Find the maximum altitude reached by the rocket
2. Find the total time of flight
3. Find the horizontal range
The Attempt at a Solution
Well I wrote down the problem and the main thing I need to figure out is a formula for related problems which give an angle and time something goes into the air with acceleration and ask for how far does it go up into the air after the power stops. I calculated for the first 3 secs it went 480 feet in the air (130+160+190). And it keeps going after that and eventually stops so I figure I need to use a formula with gravity. But I really want to figure this out because I missed a similar test question like this.
And I can't find out out the 2nd part of the problem I believe unless I figure out the first one. And for horizontal range, how does the angle affect the distance? Btw does anyone know how to make the degrees symbol or the little 2 above a number to symbolize it being squared?
