A 5.0-kg ball and a 10.0-kg ball approach each other with equal speeds of 20 m/s. If they collide perfectly inelastically, the speed of the balls just after the collision is approximately

A mass m = 2.5 kg is sliding along a frictionless table with initial speed v as shown in the figure. It strikes a coiled spring that has a force constant k = 500 N/m and compresses it a distance x2 – x1 = –5.0 cm. The initial speed v of the block was

Name a visual test for which this item was used.

The involuntary rolling of the eyes in any direction or trailing of the eyes in one direction during and after spinning (rotation) is called:

Identify the labeled vessel at #52.

You are pedaling a bicycle at 9.8 m/s. The radius of the wheels of the bicycle is 51.9 cm. The angular velocity of rotation of the wheels is

Identify the labeled structure (at #57) of the intrinsic conduction system.

Identify the labeled valve at #42.

The work-kinetic energy theorem states that

A boy and girl on ice skates face each other. The girl has a mass of 20 kg and the boy has a mass of 30 kg. The boy pushes the girl backward at a speed of 3.0 m/s. As a result of the push, the speed of the boy is
