1. The problem statement, all variables and given/known data I am investigating a scenario where a pendulum with a bob attached is released from an angle and pushes a box to a certain distance. My goal is to find the coefficient of friction between the box and the surface it moved on. I have measurements for: - mass of the bob (125 grams) - mass of the box (267.3 grams) - length of the pendulum (27 cm) - distance the box moved from its initial position (3.2 cm) - angle of release (30 degrees above the x-axis) 2. Relevant equations - 1/2(m)(v^2) = mgh - Vf = sqrt(2*g*h) - m1+v1=m2+v2 - h = L(1-cos(theta)) - Ff=μFN 3. The attempt at a solution 0.27(1-cos(30))= h = 3.62 cm sqrt (2*9.8*0.0362) = Vf = 0.84 m/s (speed before hitting the box) (0.125)(0.84)=(0.2673)(v2), v2 = 0.33 m/s (speed of the block) (9.8)(0.2673) = FN = 2.62 N I don't know where to go from here. If you could help me or point me in the right direction, I would greatly appreciate it, Thanks!
