A beam, uniform in mass, M = 89 kg and length L = 24 m, hangs by a cable supported at point B, and rotates without friction around point A. On the end far of the beam, an object of mass m = 26 kg is hanging. The beam is making an angle of θ = 25° at point A with respect to the + x-axis. The cable makes an angle φ = 21° with respect to the -x-axis at B. Assume ψ = θ + φ.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer
