Answer:
65 m/s
Explanation:
The motion of the supply along the horizontal direction is a uniform motion with constant speed. Therefore, its horizontal velocity is given by
[tex]v=\frac{d}{t}[/tex]
where
d is the distance travelled horizontally
t is the time taken
In this problem, d = 650 m and t = 10 s, so if we apply the formula we get
[tex]v=\frac{650 m}{10 s}=65.0 m/s[/tex]
