An object with a mass of 10kg starts off not moving. Then, a person pushes the object with a force of 30N to the right while friction pushes to the left with a force of 15N. If the person pushes with the same force for 30s, how far will they push the object? -
Please explain step by step

Which best represents the law of conservation of mass ?

What is a carrier wave and how does it affect what you hear on the radio

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
