Respuesta :
v1 - v0 = at
= 4.7 x 10^3 m/s^2 x 300s
= 1.4 x 10^6 m/s
hope this helps

Explanation:
Given that,
Acceleration of the treadmill, [tex]a=4.7\times 10^{-3}\ m/s^2[/tex]
Time, t = 5 min = 300 s
Acceleration is given by :
[tex]a=\dfrac{v-u}{t}[/tex]
(a) (v-u) is the change in speed.
[tex]v-u=a\times t[/tex]
[tex]v-u=4.7\times 10^{-3}\times 300[/tex]
[tex]v-u=1.41\ m/s[/tex]
So, the change in speed of the treadmill is 1.41 m/s.
(b) Initial speed of the treadmill, u = 1.7 m/s
The final speed is given by using equation as :
[tex]v=u+at[/tex]
[tex]v=1.7+4.7\times 10^{-3}\times 300[/tex]
v = 3.11 m/s
Hence, this is the required solution.
