Answer: +25 m/s
25 is a positive but if you add a negative sign, it decreases the number that you put the negative before
Hope this helps :)
Answer:
304.86 metres
Explanation:
The x and y cordinates are
and
respectively
The horizontal distance travelled, ![x=v_{ox}t=dcos\theta](https://tex.z-dn.net/?f=x%3Dv_%7Box%7Dt%3Ddcos%5Ctheta)
Making t the subject, ![t=\frac{dcos\theta}{v_{ox}}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bdcos%5Ctheta%7D%7Bv_%7Box%7D%7D)
Since
, we substitute t with the above and obtain
![0.5g(\frac{dcos\theta}{v_{ox}})^2=dsin\theta](https://tex.z-dn.net/?f=0.5g%28%5Cfrac%7Bdcos%5Ctheta%7D%7Bv_%7Box%7D%7D%29%5E2%3Ddsin%5Ctheta)
Making d the subject we obtain
![d=\frac{2v_{ox}^2sin\theta}{gcos^2\theta}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B2v_%7Box%7D%5E2sin%5Ctheta%7D%7Bgcos%5E2%5Ctheta%7D)
![d=\frac{2*30^2sin48}{9.8cos^248}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B2%2A30%5E2sin48%7D%7B9.8cos%5E248%7D)
d=304.8584
d=304.86m
