Answer:
Change in momentum is
Solution:
The momentum of any body is the product of its mass and the velocity associated with the body and is generally given by:
Now, as per the question:
Mass of the car, M = 1500 kg
The velocity in the east direction,
The velocity in the north direction,
Now, the momentum of the car in the east direction:
Now, the momentum of the car in the north direction:
Change in momentum is given by:
Now,
(Since, )
Answer:
The answer is 12.67 TMU
Explanation:
Recall that,
worker’s eyes travel distance must be = 20 in.
The perpendicular distance from her eyes to the line of travel is =24 in
What is the MTM-1 normal time in TMUs that should be allowed for the eye travel element = ?
Now,
We solve for the given problem.
Eye travel is = 15.2 * T/D
=15.2 * 20 in/24 in
so,
= 12.67 TMU
Therefore, the MTM -1 of normal time that should be allowed for the eye travel element is = 12.67 TMU
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. ... One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m
Answer:
A wheel and axle, force multipliers and a lever.
Explanation:
The short answer is no.
A simple way to see this is to try and calculate the final velocities of two particles after an elastic collision. Pick an arbitrary starting configuration (such that they will interact), and calculate their initial kinetic energy, K.
