Freight trains can produce only relatively small acceleration and decelerations. (a) what is the final velocity (in m/s) of a freight train that accelerates at a rate of 0.0600 m/s2 for 8.00 min, starting with an initial velocity of 5.00 m/s?

A wave has a wavelength of 3.3m and a speed of 5.6m/s. What is the frequency of this wave?

What is true about the speed of waves as they travel through different materials?

On which moment of inertia of an object does depend on?

The rate of change of the downward velocity of a falling object is the acceleration of gravity (10 meters/sec^2) minus the acceleration due to air resistance. Suppose that the acceleration due to air resistance is 0.

At a certain factory, 340 kg crates are dropped vertically from a packing machine onto a conveyor belt moving at 1.00 m/s. (A motor maintains the belt's constant speed.) The coefficient of kinetic friction between belt and crate is 0.400.

A hydraulic lift is used to lift a heavy box that is pushing down on a 1.5-m2 piston with a force of 1,700 N. What force needs to be exerted on a 0.12-m2 piston to lift the box?

Rauol's friend Johnny sets out from his house in the city. His displacement is 900 m 80° North of west. What is the x component of his displacement vector?

What is the relationship between gravity and mass? What is the relationship between gravity and distance?
