An object has a momentum of 4,000 kg-m/s and a mass of 115 kg. It crashes into another object that has a mass of 100 kg. If the momentum is conserved, what is the new velocity? Round to the nearest hundredth.

The radius of the merry-go-round is 10 meters. The Chile has a mass of 40 kilograms. What is the child's moment of inertia

A 2 microcoulomb charge is placed at a distance of 0.25 m away from a 3.6 microcoulomb charge. Describe the type of electrostatic force between the charges and calculate the magnitude of the electrostatic force between them.

Before a bond breaks in a chemical reaction, what happens? Neutrons in the nucleus expand. Energy is absorbed. The products get larger. An atom loses its protons.

if for every force there is an equal and opposite reaction force, how is it possible for an object to accelerate

a roller coaster is hard to stop because it has a lot of inertia. Use Newton's first law of motion to explain why you feel tossed around whenever a roller coaster goes over a hill and through a loop.

Is balancing an egg on the equinox science or pseudoscience

What does a speedometer measure? A. Average speed B. Acceleration C. Speed D. Velocity

How does increasing the amount of charge on an object affect the electric force it exerts on another charged object?

A diffraction grating is illuminated simultaneously with red light of wavelength 670 nm and light of an unknown wavelength. The fifth-order maximum of the unknown wavelength exactly overlaps the third-order maximum of the red light.
