1. The problem statement, all variables and given/known data A person is trying to jump over the pit in a car. I need to find what is the minimum speed required to make it over. This speed is calculated not from the start of the ramp, but from the take off. Drawing of all the elements Please excuse my ugly drawing :P. 2. Relevant equations Projectile motion equations (Where Time is a constant) d=vot+1/2at^2 3. The attempt at a solution So, I am trying to find the minimum velocity required to make this jump. We know the θ of the Ram is 25°. We also know that the left side is 15m, and the right is 16m. From there, we can judge that the Ramp is more like this. Illustration of my triangle We know the right side is 1m higher than the left, so we have to account for that in making our triangle. We can calculate our 2nd θ using Tan = 1/15. This yields a theta of 3.8°. To calculate the velocity required, i used projectile motion (using time as the only constant) Vx | Vy d= 15m Vf= X V=? Vo=0 T= ? <--------> T=? d=1m a=-9.8m/s^2 Calculate T using d=VoT+1/2at^2 1= 0 + 1/2(9.8)t^2 1=4.9t^2 t=0.45s Calculate how fast the person needs to go to make the jump D=V * T 15 = 0.45V V= 33 m/s Does that make sense? I feel like I did something wrong as I did not use the 25°. Any help is much appreciated, and if you need more info/clarification, I will obliged.
