Superman ferma in 5,0 ∙10^(-3) s un treno inizialmente in corsa alla velocitá di 216km/h. Qual é l’accelerazione media del treno
kotykmax [81]

Answer:

1.2*10^4 m/s^2

Explanation:

The formula to find average acceleration is a=Δv/Δt.

Convert 216 km/hr to m/s

216 km/hr * 1000 m/km * 1 hr/60 mins * 1 min/60 secs = 60 m/s

So a= (60 m/s)/(5.0*10^-3) = 12000 m/s^2

Put that into scientific notation to get 1.2*10^4 m/s^2

The basketball coach tells his team to run sprints back and forth across the court, which is 30 m long. They start at the left e
sp2606 [1]

Distance is the total length of an object's path. Displacement is the overall change in position, ie. how far an object is from its initial position.


The court is 30 m long, so a path going back and forth once is 60 m long. Going along this path 6 times totals 360 m.


The end point is the same as the starting point, so the displacement is 0 m.

describe how acceleration and velocity are related and specify if these are scalar and vector quantities
vitfil [10]

Velocity is the rate of change in distance over change in time, this can be written as:

v = Δd / Δt

While acceleration is the rate of change in velocity over change in time, this is written as:

a = Δv / Δt

 

<span>Both quantities are vector quantities because negative values means that the acceleration or velocity is acting on the opposite direction.</span>
