Hello. Can someone tell me what area of phisics should I study to better understand this exercise and also what should I do to solve this exercise please?
A man pulls a small sledge with a force F ⃗ of intensity equal to 50.0 N and that makes an angle with the horizontal θ = 30º (see figure). The sled moves horizontally and the resistance that the snow offers to the movement of the sled results in a frictional force of intensity F a = 15 N. the sled has a mass of 20 kg. Determine:
a) the normal reaction to which the sled is subjected;
b) the resulting horizontal force on the sled;
c) the acceleration acquired by the sled;
d) the speed acquired by the sled after 10 s, assuming it started from rest.
(Use g = 10.0 m ∙ s -2 ).
