Astudent pulls a sled of mass m = 82.0 kg with a force of f = 160n, and the force makes an angle of θ = 15 degrees with respect to the horizontal. ignoring friction the normal force exerted on the sled by the ground is a) 649.05n;
b) 762.2n;
c) 527.90n;
d) 845.01n;

B

Explanation:

Given

mass of sledge=82 kg

Force on sledge=160 N

degree

force has two component sin and cos

Normal reaction

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.
