Consider the ladder in 8.15. Compute the normal force again,
assuming a 75 kg man is standing on the ladder (a) at its midpoint
and (b) four fifths of the way up the latter.
I posted this question earlier but was very confused on how it
was answered and laid out. I am not understanding how to go about
this or what formulas to use.

2. A mass of m kilograms (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixed to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The...

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....
