Hello, I'm working on my first year engineering project. I'm an electrical engineering major but this is a general engineering course. I'd like to know how I could figure out how much weight I would need to put on the wheels of a cart that is going to push a 2kg object (for about 3 feet). The motor will apply 2.6N of force in the x direction with wheels that are r=0.05m. The motor is capable of 5000RPM at full speed, but they can operate a low RPM for a short amount of time with higher torque, which is how I got the 2.6N figure. However, if the cart is too light, the wheels will just spin wildly and not move the 2kg object anywhere. How much weight would the cart need to be to get the book to move? Thanks!
