Step-by-step explanation:
try this option, all the details are in the attachment.
From the moment the friend passes the bicyclist, his friend covers a distance over time t of (3.63 m/s)*t.
The bicyclist covers a distance of 1/2*(2.11 m/s^2)*t^2. They meet when these distances are equal:
3.63 t = 1.055 t^2 ==> 1.055 t^2 - 3.63 t = 0
==> t = 0 s or t = 3.44 s
No, because if they were equal the second equation should be 225/(15x3), not (15/3).
Answer:
it should be 12
Step-by-step explanation:
because 3x4=12
7 + 7 + 5 + 5 (two sides are 7 and two sides are 5) = 24
