Answer:
![F = 551.6 N](https://tex.z-dn.net/?f=F%20%3D%20551.6%20N)
Explanation:
When two players are pulling the sled by same force inclined at 50 degree Angle so the net force is given as
![F_{net} = \sqrt{F^2 + F^2 + 2F^2cos\theta}](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20%5Csqrt%7BF%5E2%20%2B%20F%5E2%20%2B%202F%5E2cos%5Ctheta%7D)
![F_{net} = F\sqrt{2 + 2cos\theta}](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20F%5Csqrt%7B2%20%2B%202cos%5Ctheta%7D)
![F_{net} = F\sqrt{2 + 2cos50}](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20F%5Csqrt%7B2%20%2B%202cos50%7D)
![F_{net} = 1.81 F](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%201.81%20F)
now since the sled is moving with uniform speed so
![F_{net} = F_f](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20F_f)
now we have
![1.81 F = 1000](https://tex.z-dn.net/?f=1.81%20F%20%3D%201000)
![F = 551.6 N](https://tex.z-dn.net/?f=F%20%3D%20551.6%20N)
Answer:
The equation to finding acceleration:
F/m=a
F= 20N
m= 4 kg
A= 20/4
A=5
<u>Acceleration= 5 m/s^2</u>

Answer:
True.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
![Velocity = \frac{distance}{time}](https://tex.z-dn.net/?f=Velocity%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
Simply stated, a vector quantity has both magnitude and direction.
Thus, a vector quantity is: A deer running 15 meters per second due west.
