Answer:
The radius of the curve that Car 2 travels on is 380 meters.
Explanation:
Speed of car 1, 
Radius of the circular arc, 
Car 2 has twice the speed of Car 1, 
We need to find the radius of the curve that Car 2 travels on have to be in order for both cars to have the same centripetal acceleration. We know that the centripetal acceleration is given by :

According to given condition,


On solving we get :

So, the radius of the curve that Car 2 travels on is 380 meters. Hence, this is the required solution.
Answer:
I'm pretty sure its 3m/s^2 for the acceleration but I don't know the force part sorry .
Explanation:
15m/s - 0m/s divided by 5 s = 3m/s
I'm no expert or anything so I could be wrong but this is the best I can give you. Sorry
Answer:
B object at rest
Explanation:
object at rest means it wouldn't be moving, like a parked car or sleeping person therefore, B is the correct answer
Answer: thermal
Explanation:
Moving particles transfer thermal energy through a fluid by forming convection currents.
An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
