I’m pretty sure 14 is mutations
Explanation:
Given that,
Initial velocity, u = 11.3 m/s
Angle above the horizontal, ![\theta=35^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D35%5E%7B%5Ccirc%7D)
Time of flight :
![t=\dfrac{2u\sin\theta}{g}\\\\t=\dfrac{2\times 11.3\times \sin(35)}{9.8}\\\\t=1.32\ s](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B2u%5Csin%5Ctheta%7D%7Bg%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B2%5Ctimes%2011.3%5Ctimes%20%5Csin%2835%29%7D%7B9.8%7D%5C%5C%5C%5Ct%3D1.32%5C%20s)
Horizontal distance traveled is given by :
x = ut
x = 11.3 m/s × 1.32 s
x = 14.916 m
Maximum height is given by :
![H=\dfrac{u^2\sin^2\theta}{2g}\\\\H=\dfrac{(11.3)^2\times \sin^2(35)}{2\times 9.8}\\\\H=2.14\ m](https://tex.z-dn.net/?f=H%3D%5Cdfrac%7Bu%5E2%5Csin%5E2%5Ctheta%7D%7B2g%7D%5C%5C%5C%5CH%3D%5Cdfrac%7B%2811.3%29%5E2%5Ctimes%20%5Csin%5E2%2835%29%7D%7B2%5Ctimes%209.8%7D%5C%5C%5C%5CH%3D2.14%5C%20m)
Hence, time of flight is 1.32 s, horizontal distance is 14.916 m and maximum height is 2.14 m.
Answer:
h = 11.47 m
Explanation:
Initial speed pf the t-shirt gun is 15 m/s
We need to find the maximum distance covered by the t-shirt. It is based on the conservation of energy. The maximum distance covered is given by :
![h=\dfrac{u^2}{2g}\\\\h=\dfrac{(15)^2}{2\times 9.8}\\\\h=11.47\ m](https://tex.z-dn.net/?f=h%3D%5Cdfrac%7Bu%5E2%7D%7B2g%7D%5C%5C%5C%5Ch%3D%5Cdfrac%7B%2815%29%5E2%7D%7B2%5Ctimes%209.8%7D%5C%5C%5C%5Ch%3D11.47%5C%20m)
So, it will cover a distance of 11.47 m.
