Physics-Please check if I did this correctly
I posted this question this morning but I'm not sure of the response Damon provided. I did it once but then I updated it later in this at the bottom- please check booth of my answers. If you were in a rotor style ride and the riders accelerate until the speed of ride is ...

Science (Help, please!)
"Toy Car A" is propelled by elastic force. The other forces acting on the car are gravity (pulling the car down) and friction force (between the car and the floor). What UNBALANCED forces are acting on the car? "Toy Car B" is propelled by air resistance. The other forces ...
