Answer:
v = 72 km / h
Explanation:
The definition of average speed is the distance traveled between the time interval
v = Δx / Δt
let's find the distance traveled
x = 60 + 30
x = 90 km
time spent, all time must be included, travel time and when stopped
t = 0.45 + 0.15 + 0.5+ 0.15
t = 1.25 h
we substitute in the initial equation
v = 90 / 1.25
v = 72 km / h

The first runner because it is very clear that accelarition depends on the time and we know that the time in this case is pretty simple
I think the correct answer from the choices listed above is option C. The change in the statement that would make a more powerful goal would be to make <span>it measurable by explaining how far away the target is. Hope this answers the question. Have a nice day.</span>
Answer:
8.2 m/s²
Explanation:
m = mass of the block
μ = Coefficient of kinetic friction = 0.17
= Normal force on the block by the ramp
= kinetic frictional force
Force equation perpendicular to ramp surface is given as
Kinetic frictional force is given as
Force equation parallel to ramp surface is given as
m/s²
