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

The acceleration of the sled is .18m/s2
The maximum force of static friction acting on the sled is 147.15 N (50 kg x 9.81 m/s^2 x 0.30). Once the force exceeds this value, the sled will start moving. Once the sled is in motion, the force of sliding friction acting on it will be 49.05 N (50 kg x 9.81 m/s^2 x 0.10).
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.
The Dog pulls with force (equal action) throws snow back (opposite action) pulling the sled (reaction). SO its newton's Third law of motion. PS This belongs in a physics, science or math section. Not Dogs
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.
A dog sled idiom is a sled that men go on to get pulled by huskies
The force that holds you to a sled when it starts moving is friction between your body and the sled, as well as the force of gravity acting on you downwards. As the sled accelerates, friction between your body and the sled helps keep you in place and in motion together.
The acceleration is caused by the force of gravity on the sled combined with the force you exert on the sled by pushing it.

To keep a sled accelerating downhill, the force of gravity must be greater than the force of friction acting against the sled. This allows gravity to overcome the frictional force and propel the sled forward.
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.
Friction is the force that keeps you from sliding off a sled when it starts moving. When you sit on a sled, the friction between the sled and your clothing provides the necessary grip to keep you in place as the sled accelerates.
The acceleration of the sled is .18m/s2
Yes, when a sled is accelerating downhill, the force of gravity pulling the sled downhill must be greater than the normal force acting in the opposite direction to overcome friction and any other resistive forces. This difference in force is what allows the sled to accelerate downhill.
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
A sled accelerates downhill when the force of gravity pulling it downhill is greater than the force of friction and air resistance acting against it. This difference creates a net force that causes the sled to accelerate. The normal force from the surface helps support the sled against gravity but does not impact its acceleration directly.
