Answer:
a) a = - 0.0833 m / s², b) t = 4.4 s
Explanation:
a) this is a kinematics exercise where the acceleration is along the inclined plane
v = v₀ - a t
a = v₀ - v / t
a = 3 - 8/60
a = - 0.0833 m / s²
b) in this case the final velocity is zero
v = v₀ - a t
0 = v₀ - at
t = v₀ / a
t = 28 / 6.4
t = 4.375 s
t = 4.4 s

Answer:
Making a quick cut left to intercept a pass
Explanation:
It takes more energe to do than running
The answer is a
the equation needs to be balanced. There are fewer oxygen atoms in the equation than hydrogen or a carbon
