In order to get an object moving, you must push harder on it than it pushes back on you.

You throw a baseball directly upward at time t = 0 at an initial speed of 12.3 m/s. what is the maximum height the ball reaches above where it leaves your hand? at what times does the ball pass through half the maximum height? ignore air resistance and take g = 9.80 m/s2.

State the right hand rule of the direction of magnetic field in a conductor carrying current

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.
