a 1.5 kg object is whirled around on the end of a string that is 1.8 m long. the object's linear speed is 5.6 m/s. what is the angular momentum of the object?

Explanation:

The angular momentum of an object is given by the following formula:

Where:

is the distance between the object and the origin (the center of the circular motion)

is the mass of the object

is the linear speed of the object

since the oject is moving in circular motion, is perpendicular to , which is the object's linear momentum.

Solving with the givrn data:

This is the object's angular momentum

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
