Her magnitude of deceleration on the ice would be 15.126m/s
Answer:
Friction = 5 N
Explanation:
As we know that block is moving at constant speed
So the acceleration of the block is zero
So we will have

for net force to be zero
Force exerted on the object by external system must be counter balanced by the force of friction
So we have

so we have

The charge on the electron is 1.6x10^-19C. So, 10^24 of them will be a charge of 1.6x10^5C, F = q1xq2/[(4pi epsilon nought)r^2]
Urbanization can cause a lot of problems for nature such as pollution, global warming, and depletion of wildlife such as plants and animals.
