Question

1. Consider a particle, bead, slider, car, or anything that can be treated as a point mass starting at y=?=30 m and following the curve shown with ,?c=10 m and r=5 ??m. What are the velocities and accelerations at points A-D?1.    a bead on a wire 30m high is released and reaches point A, where is loops twice towards the right. what is the velocity and acceleration at point A-D? point A is at 20m directly below from starting point. Point B is 10m at the bottom of the first loop. point C is in between the A,B and on the left side of the loop. point D is at 20m at the top of the second loop.

Explanation / Answer

at the point A...

(1/2mV^2)=mgh

V^2=2gh

V^2=9.8*2*20(h=from to starting point)

=392

V=19.79m/s(at the point A)

velocity at the point D

(1/2mv^2)=mgh (h=15m from starting point)

v^2=294

v=17.14m/s
