Answer:
1/2
Explanation:
- ay = -gcosФ , ax = gsinФ
- Vy =V0cosФ and Vx =V0 sinФ
- tb =2Vy/-ay =2V0/g
- Δx = Vxt + 0.5axt²
- d12 =V0 sinФ(2V0/2) +0.5sinФ(2V0/g) =4V0²sinФ/g
- d13 =V0sinФ(4V0/g) + 0.5gsinФ(4V0/g) =12V0²sinФ/g
- Then d23 = d13 - d12 = (8V0² - sinФ)/g
- And the Final expression of their ratio, d12/d23 = 1/2
