Webinextensible string. Particle A is held at rest on a rough horizontal table with the string passing over a smooth pulley ﬁxed at the edge of the table. The coefﬁcient of friction between A and the table is 0.2. ParticleB hangs verticallybelow the pulley at a height of 0.5m above the ﬂoor (see diagram). Web1 One end of a light inextensible string is attached to a block. The string makes an angle of 60Å above the horizontal and is used to pull the block in a straight line on a horizontal ﬂoor with acceleration 0.5ms−2. The tension in the string is 8N. The block starts to move with speed 0.3ms−1. For the ﬁrst 5s of the block’s motion, ﬁnd mabel bell obituary
