Hi gang,
I've been reading for a while and now need some help of my own. Thanks in advance.
I'm currently planning a project where I'm going to demonstrate a launch of an RC car off the flat roof of a building. The height of the roof is 25'. I figure the RC car will go 25mph, and the ramp angle is about 25º. The ground below is flat and the car will be destroyed--that's OK though.
I've put together a spreadsheet that attempts to model the launch and descent, including plotting the launch trajectory. I THINK I've done everything correctly but would love to have another set of eyeballs peak at it before I distribute the datasheet. The file is attached.
Main concerns:
1. My calculated distance traveled (57.43') doesn't match up with the location on the plot where RC car hits the ground (looks to be just over 60').
2. Will it really travel 60'? That's hard to imagine.
3. I haven't included any calculations for air resistance...
Thanks in advance,
Denver
