Hello- I have a projectile problem that I would like some advice on to approach.
A rocket is launched at 53 degrees with 75 m/s, and 25 m/s squared for twenty five seconds.
The question is how high does it go, total time in flight, and finally the horizontal range. Book answer 24,000 m, 152 sec, 78,000 m.
I approached the problem by breaking it up into two phases- rocket motor on for 25 seconds, second phase motor off and start of return trip.
The problem seem to center around the acceleration factor and the what happens to projectile when the motor is off.
I was close on my answers but my work was not a thing of beauty, I am doing my work with a high school text and need to stay at that level before moving on to higher study material.
Thanks in advance for your time and trouble
