1. If a 30kg object experiences a normal force of 210N when traveling down a ramp, what is the angle of incline? Also, calculate the force of friction and the coefficient of friction.
Answers: μ(mu)=0.98
Θ=44.5 degrees
But please show work and all equations/variables used.
normal force=mg*cosTheta
solve for theta
forcefriction=normalforce*mu*sinTheta
the second equation cannot be solved without more information, such as the object is going down at constant speed. Otherwise, not solvable.
