You are dragging a block on a surface with friction at a steady speed of 2 m/s and exert a force of 5 n to do so. what is the force of friction?

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

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

be subject to a force andchange its motion
