Newton's first law is called inertia, or the force an object has to resist unbalanced forces that are placed upon it. The more mass an object has, the more inertia an object has. The less mass an object has, the less inertia an object has.
.. The weight of the loaded sled is 2200 N. The coefficient of friction is 0.15. How hard must the dogs pull so that their effort just equals the frictional force? ... to move after the light changes from red to green A team of dogs pulls a sled across the snow. ... 2) pulling force of dogs fL = us N = 0.15 x2200 = 330 <span>N

The average speed will be:
Total distance travelled divided by time taken
Total distance (in metres)= 80+125+45=250
Total time (minutes) =10
250/10
=25
Thus Mary's average speed is 25 metres per minute.
