Ok, a simple vector problem. I found all the data, but have no idea to set it up. Here is what I am trying to do... I want to find it Car1 can ramp over the top of Car2, without hitting it. Both cars are ramping off the same ramp, and lets assume air resistance will not be significant. Car1 v = 72 m/s Weight = 1666 kgs Length = 4.6 m Car2 v = 34 m/s Weight = 1590 kgs Length = 4.5 m Height = 1.27 m I am going to assume both cars are ramping off the ramp at the same time, and the angle of their ramp is 13 degrees. Also, the 'v' value is when they are leaving the ramp. Timely answers are appreciated, Thanks.
