A 120-newton box is pulled by a 48-newton horizontal force across a horizontal surface at constant velocity. The coefficient of kinetic friction between the box and the horizontal surface is

A 0.14-kilogram lacrosse ball, traveling west at 17 meters per second, is brought to rest with a 0.21-kilogram lacrosse stick. If the force applied by the lacrosse stick on the ball is 220 newtons east, the force applied by the ball on the stick is

A wood block is pulled at constant velocity across a horizontal wood floor. Which type of energy increases in this block-floor system as the block moves?

A train blows its horn, which emits a uniform sound as the train approaches a stationary observer. The observer hears a sound that has a

A total energy of 5.0 joules is used to move an electron from position A to position B in a uniform electric field. What is the potential difference between positions A and B?

Compared to box A, box B has a gravitational potential energy relative to the floor that is

Four wires are tested for electrical conductivity. All the wires have the same length and the same cross-sectional area, but are made of different metals. Which wire has the highest conductivity at 20°C?

A 4.0-kilogram mass is initially at rest on a horizontal, frictionless surface. A constant 2.0-newton force to the east is applied to the mass for a 5.0-second interval. As a result of this action, the mass acquires a
