Answer:
nearly 2 days or less hes fast but not that fast
Explanation:
but maybe he can run it in five minutes
<span>NO.
Air resistance does not affect the motion of a falling object differently when the mass is greater because the mass of an object does not in any way affect the speed of falling due to gravity, and air resistance depends only on the speed of the object and its surface area.</span>

Answer:
93 m
Explanation:
We need to find the resultant displacement.
Let's take north as positive y-direction and east as positive direction. We have
- Displacement 1 is 51 m to the north, so the two components are
![x_1 =0\\y_1 = 51 m](https://tex.z-dn.net/?f=x_1%20%3D0%5C%5Cy_1%20%3D%2051%20m)
- Displacement 2 is 45 m
north of east, so the two components are
![x_1 = (45)cos 60^{\circ}=22.5 m\\y_1 = (45) sin 60^{\circ}=39.0 m](https://tex.z-dn.net/?f=x_1%20%3D%20%2845%29cos%2060%5E%7B%5Ccirc%7D%3D22.5%20m%5C%5Cy_1%20%3D%20%2845%29%20sin%2060%5E%7B%5Ccirc%7D%3D39.0%20m)
So to find the resultant displacement we have to sum the components along each direction:
![x=x_1 + x_2 = 0+22.5 m = 22.5 m\\y = y_1 + y_2 = 51 m +39.0 m = 90.0 m](https://tex.z-dn.net/?f=x%3Dx_1%20%2B%20x_2%20%3D%200%2B22.5%20m%20%3D%2022.5%20m%5C%5Cy%20%3D%20y_1%20%2B%20y_2%20%3D%2051%20m%20%2B39.0%20m%20%3D%2090.0%20m)
And the magnitude of the resultant displacement is
![m=\sqrt{x^2+y^2}=\sqrt{(22.5 m)^2+(90.0 m)^2}=92.8 m \sim 93 m](https://tex.z-dn.net/?f=m%3D%5Csqrt%7Bx%5E2%2By%5E2%7D%3D%5Csqrt%7B%2822.5%20m%29%5E2%2B%2890.0%20m%29%5E2%7D%3D92.8%20m%20%5Csim%2093%20m)
