jake drags a sled of mass 10 kg across the snow. the sled is attached to a rope that he pulls with a force of 30 n at an angle o
f 25°. if there is no friction, what is the normal force acting on the sled?
2 answers:
Answer:
The normal force is 85,42 N
Explanation:
There is no friction force, therefore there is no relationship between the normal force and the friction.
We can find the normal force using a free body diagram and check the forces that are acting on the sled. The total forces are equal to 0 because there is no movement in the y-axis. The movement exists only on the x-axis.
