well as per the formula F=ma
applying the formula, it make
F=ma
30=15*a
a=30/15
a=2
So acceleration is 2ms-2

Travios is a sled pulled by dogs
The acceleration of the sled is .18m/s2
The law of motion that relates to a dog pulling a sled is Newton's third law of motion. It states that for every action, there is an equal and opposite reaction. In this case, as the dog exerts force on the sled by pulling it forward, there is an equal and opposite force exerted by the sled on the dog, enabling the forward movement of the sled.
You may have to determine the coeffient by experiment. It is impossible to include every possible combination of materials.This can build a "sled" and place one material flat along the bottom. A thirty pound sled is common. Pull this weight across a flat surface covered by the other material. Measure the amount of force required to initiate movement using a spring scale (like a fish scale). This force in pounds divided by the weight of the sled in pounds will equal the coefficient of static friction. To determine the dynamic coefficient of friction, measure the pounds required to keep the sled in motion. This will be somewhat less than the force required to start the sled in motion.The coefficient for vinyl and nylon should be quite low.
Answer 1 - This is because of friction. Answer 2- This is because the force you exert must be in the same direction as the objects motion. So the part pulling forward does work, when the force pulling upward does not.
A dog sled idiom is a sled that men go on to get pulled by huskies
The acceleration is caused by the force of gravity on the sled combined with the force you exert on the sled by pushing it.

First iditarod was made to deliver mails on the sled which is pulled by the dog.Now they use it for sled dog race
It's a sled pulled by dogs. It's that simple.
Ignore the kinetic friction coefficient, that is only in the problem to trick you. If the force pulling the sled is parallel to the ground, then the problem should be pretty easy. Acceleration due to gravity = 9.8 m/s^2

Not at all. The force of gravity must be greater than the friction force, but if the sled is on any kind of slope, then it doesn't matter what the normal force is.
The force of friction is proportional to the force which surfaces press against each other. Since two people will cause the sled to push harder on the snow then one person, the friction will be greater for two people on the sled.
A komatik is an Eskimo sled. It is designed to travel on snow and ice, and made of wooden runners and crossbars lashed with rawhide.
Overland by dog sled or animal pulled wagon. By water when sea ice is not solid. Or, by air.
