the average velocity of a duck is zero as it goes from t=0 to t=120 s. describe the displacement of the duck for that interval

Michael and Isabella are working together on an assignment. They must search some illustrations to find an example of heat transfer by convection.

Calculate the velocity of the boat immediately after, assuming it was initially at rest. The mass of the child is 25.0 kg and that of the boat is 30.0 kg. (Take the package's direction of motion as positive.)

A paperboy rode his bike at 3 m/s. After being chased by a dog for 8 seconds, he was traveling 6m/s. What is his acceleration? Your answer

A moving object has a kinetic energy of 150 j and a momentum with a magnitude of 30.0 kg•m/s. determine the mass and speed of the object

How does changing depth affect water pressure

The mass of a rigid rod is 0.60 kg and its length is 39.0 cm. Calculate the moment of inertia (in kg · m2) for the rod if it is pivoted about an axis through the center of mass of the rod. (Assume the axis is perpendicular to the rod.
