Concrete is not a polymer which Nylon, and Kevlar are
Answer:
The final velocity of the runner at the end of the given time is 2.7 m/s.
Explanation:
Given;
initial velocity of the runner, u = 1.1 m/s
constant acceleration, a = 0.8 m/s²
time of motion, t = 2.0 s
The velocity of the runner at the end of the given time is calculate as;
where;
v is the final velocity of the runner at the end of the given time;
v = 1.1 + (0.8)(2)
v = 2.7 m/s
Therefore, the final velocity of the runner at the end of the given time is 2.7 m/s.
force times gravity (FG) =mass times gravity (mg)
To present your findings/data
The wings on the plane help balance a force and it remains flying from the fan of the plane and gravity . When its unbalanced most likely the plane will crash .
