<h2>Answer:</h2>
Answers in the explanation
<h2>Explanation:</h2>The term speed is used to denote distance traveled divided by time. This can be expressed in a mathematical language as follows:
The cart with Low fan speed:
The cart with Medium fan speed:
The cart with High fan speed:
B) initial speed (u)=3
final speed (v)=8
time (t)= 10
acceleration (a)=?
v=u+at
8=3+a(10)
5=10a
a=1/2= 0.5 m/s²
c)displacement (s)=?
1st section of journey
v ²=u ²+2as
8 ²=3 ²+2(0.5)s
64=9+1s
s=55meters
2nd section of journey
a=0
t=7
u=8
s=?
s=ut+1/2at²
s=8(7)+1/2(0)(7 ²)
s=56 meters
56+55= 111 meters
(For graph x axis =time (sec) & y axis= velocity (m/s))
