Answer:
Explanation:
according to einstein's formulae E=mc2 1kg of mass is equivalent to (9joules when rounded off )
in this situation we ignore the bridge height and work hand in hand with the relativity and force
so...if you do the conversion you will find the suitable answer which is 16.9J
Answer: 60.0 kg*m/s north.
Explanation: The linear momentum is a verctor, it has magnitude and direction. Also the momentun is proportional to the mass multiplier the velocity.
P=m*V ( vector)
1. the change in position of an object from start to finish, a vector quantity . . . . .<em> displacement</em>
2. a portion of space that contains a value for a measurable quantity at every point in space . . . . .<em> field </em>
3. speed = (distance) / <em>(time to cover the distance)</em>
4. the length of the entire path an object travels from start to finish . . . . . <em>distance</em>
5. a measurement that has both magnitude and direction . . . . . <em>vector</em>
6. a change in displacement with respect to time . . . . .<em> velocity</em>
7. a mental or physical construct or description that describes a physical phenomenon . . . . . <em>model</em>
8. a change in velocity with respect to time . . . . . <em>acceleration</em>
9. a measurement that only expresses magnitude, such as time, temperature, distance, and speed . . . . . <em>scalar</em>
10. objects that are thrown or launched in the air and are subject to gravity . . . . . <em>projectile</em>
Answer:No
Explanation:
Radiant energy is kinetic energy.
