A moving walkway has a speed of 0.4 m/s to the east. A Stationary observer sees a man walking on the walkway with a velocity of 0.3 m/s to the east. What is the man's velocity relative to the moving walkway?

What if a wave reaches a type of matter it cannot pass through? Does it just stop moving? If not, where does it go?

Describing motion using words instead of numbers is called ... kinematics?

An automobile with a mass of 1450 kg is parked on a moving flatbed railcar; the flatbed is 1.50 m above the ground. The railcar has a mass of 38500 kg and is moving to the right at a constant speed of 8.70 m/s on a frictionless rail.

The cathode-ray tube is a direct application of which of the following? The effects of bar magnets in the presence of a magnetic field. The movement of charges through a circuit. The acceleration of electrons through an electric field.

What is the mass of a bicycle moving at 8ms with ke of 384j?

What is the gravity on the moon

Degausser creates a magnetic field that erases data from magnetic storage media. a. True b. False

Which ever changes during a physical change?

Calculate the acceleration if you push with a 20 n horizontal force on a 4 kg block on a horizontal friction-free air table.

A horizontal force of 30 n pulls a block of mass 2.5 kg across a level floor. the coefficient of kinetic friction between the block and the floor is μk = 0.25. if the block begins with a speed of 7.
