Answer:
500Km
Explanation:
This question is an example of speed, distance, time.
The formula for working out the distance is: 
To work this out you would need to multiply the speed of 200Km/h by the time of 2.5 hours, this gives you 500 Km. This is because the formula to work out the distance is speed * time.
In adittion, if the train is traveling at 200km per hour then that means that over the course of an hour the distance travelled would be 200Km. So, by multiplying the speed by the time you are working out how far it travelled in that given time.
1) Multiply 200 by 2.5.
I'm pretty sure that the answer is gravity. I really hope this helps!
Since the crate is moving at constant velocity the net force on the crate is zero. Since the crate is moving we are referring to the coefficient of dynamic friction. R is the reaction and is equal to the weight of the block mg. The effort is now doubled so the forces on the block are not balance
Hello, use the formula:
Pe = mgh
Data:
Pe = Potential energy = ¿?
m = Mass = 48 kg
g = Gravity = 9,81 m/s²
h = Height = 7 m
Replacing according our data:
Pe = 48 kg * 9,81 m/s² * 7 m
Pe =3296,16 J
The potential energy of the skateboarder is 3296,16 Joules
Answer:
Reaction force = Weight
the force exerted by A on B is equal.
M1a = M2a
Explanation: I think the answer is right if wrong message me.
