They do not react with or chemically bond to each other.
Answer:
![\theta=82.87^0](https://tex.z-dn.net/?f=%5Ctheta%3D82.87%5E0)
u = 44.44 m/s
Explanation:
given,
horizontal displacement = 50 m
maximum height = 100 m
initial velocity (v₀) = ?
launching angle(θ) = ?
using formula
........(1)
.........(2)
dividing equation (2)/(1)
![\dfrac{h}{R} = \dfrac{\dfrac{u^2sin\theta}{2g}}{\dfrac{u^2sin2\theta}{g}}](https://tex.z-dn.net/?f=%5Cdfrac%7Bh%7D%7BR%7D%20%3D%20%5Cdfrac%7B%5Cdfrac%7Bu%5E2sin%5Ctheta%7D%7B2g%7D%7D%7B%5Cdfrac%7Bu%5E2sin2%5Ctheta%7D%7Bg%7D%7D)
![\dfrac{h}{R} =\dfrac{sin^2\theta}{2sin2\theta}](https://tex.z-dn.net/?f=%5Cdfrac%7Bh%7D%7BR%7D%20%3D%5Cdfrac%7Bsin%5E2%5Ctheta%7D%7B2sin2%5Ctheta%7D)
![\dfrac{4h}{R} =tan \theta](https://tex.z-dn.net/?f=%5Cdfrac%7B4h%7D%7BR%7D%20%3Dtan%20%5Ctheta)
![\theta= tan{-1}{\dfrac{4\times 100}{50}}](https://tex.z-dn.net/?f=%5Ctheta%3D%20tan%7B-1%7D%7B%5Cdfrac%7B4%5Ctimes%20100%7D%7B50%7D%7D)
![\theta=82.87^0](https://tex.z-dn.net/?f=%5Ctheta%3D82.87%5E0)
now using equation (2)
![100 = \dfrac{u^2sin82.87^0}{2\times 9.81}](https://tex.z-dn.net/?f=100%20%3D%20%5Cdfrac%7Bu%5E2sin82.87%5E0%7D%7B2%5Ctimes%209.81%7D)
u = 44.44 m/s
