A family drives 600 miles in 2 days. The second day they drive 120 miles less than the first day How many miles did they drive the first day?
A 10 ohm resistor is connected in series with a 15 ohm resistor. If this circuit is connected to a 9 volt battery, what will be the resultant current?
When I have (2x)^2 2x on the paper the 2x to the right is right after the squared. So its (((2x) squared 2x) squared 2x) squared
How would you go about doing this problem? I've tried and with the answer given I still can't figure it out. If anyone could explain it would be greatly appreciated! (((2x)^2 2x)^2 2x)^2

You are the designer of a school bus and would like to know what the maximum stopping distance is that will ensure the students to remain in their seats. The coefficient of static friction for the passenger and the bus seat is .5, and the coefficient of kinetic friction for th...
Two people push on a box that has a mass of 10kg, the person on the right has a mass of 86kg and applies a horizontal force of 50N. The person on the left has a mass of 45kg. The coefficient of kinetic friction between the box and the floor is .2, the coefficient of static fri...
Two blocks, (Mass of block 1 = 2.3kg, Mass of block 2 = 1.2kg), are in contact on a frictionless table. If a horizontal force of 3.2N is applied to the larger block, what is the acceleration of the smaller block. Describe all external forces that are acting on the two blocks
You have setup an experiment with two 50g masses attached to strings that are connected on opposite sides of a scale that measures weight in Newtons. a.) What is the reading on the scale? b.) The whole system is now moving to the left at a speed of 10m/s. What is the reading o...
