Answer:
105.1N
Explanation:
According to the newton second law

Since the acceleration is zero, then;

Since;

Given the following
mass of ladder m = 14kg
acceleration due to gravity g = 9.8m/s²
θ = 50°
Substitute

Hence the magnitude of the friction force (in N) exerted on the ladder in the point of contact with the horizontal surface is 105.1N
The answer is C adding more mass(Tape) to the balls(No homo) would increase the gravitational pull.
When you melt a solid the heat creates energy, when you heat up molecules they will move quicker and start to somewhat break apart into a liquid structure.
velocity describes speed with direction.
You are almost there, often you are given a mass. But, here you already have a force. You just need to use:<span>W=Fd</span>Where W is work done, F is force, d is distance. Units of work will be Nm
