Answer:
[tex]v(t=120)=36m/s\\\\d(t=120)=2160 m[/tex]
Explanation:
t=2minutes = 120 seconds:
t=120s
a=0,3m/s²
The cart starting from rest, then: vo=0m/s
We know that:
[tex]v(t)=vo+at[/tex]
[tex]v(t)=0,3t[/tex]
After t=120 s the velocity are:
[tex]v(120)=0,3*120\\v(120)=36m/s[/tex]
We know that:
[tex]d(t)=do+vo*t+\frac{a}{2}*t^{2}[/tex]
vo=0m/s
do=0m/s
The distance after t=120s are:
[tex]d(120)=0,3*\frac{120*120}{2} \\d(120)=36*60\\d(120)=2160 m[/tex]
