It depends on your weight like if you weight 150 lbs. than your maximum income should be 150 grams. Per day.
Answer:
Explanation:
The kinetic force of friction is:
Before calculating work, it is require to determine if force exerted on the crate is enough to move it at least. The equation of equilibrium for the crate is:
The acceleration experimented by the crate is:
This positive result indicates that motion is physically reasonable. Hence, the work done by the force of friction is:
Over time there can be dead animals and leaves or other things that could have been decomposed into that soil.
Answer:
speed of white ball is 1.13 m/s and speed of black ball is 2.78 m/s
initial kinetic energy = final kinetic energy
Explanation:
Since there is no external force on the system of two balls so here total momentum of two balls initially must be equal to the total momentum of two balls after collision
So we will have
momentum conservation along x direction
now plug in all values in it
so we have
similarly in Y direction we have
now plug in all values in it
so we have
now from 1st equation we have
so speed of white ball is 1.13 m/s and speed of black ball is 2.78 m/s
Also we know that since this is an elastic collision so here kinetic energy is always conserved to
initial kinetic energy = final kinetic energy
