18M.2.HL.TZ1.c.i

An elastic climbing rope is tested by fixing one end of the rope to the top of a crane. The other end of the rope is connected to a block which is initially at position A. The block is released from rest. The mass of the rope is negligible.

M18/4/PHYSI/SP2/ENG/TZ1/01

The unextended length of the rope is 60.0 m. From position A to position B, the block falls freely.

For the rope and block, describe the energy changes that take place

between A and B.

Markscheme

(loss in) gravitational potential energy (of block) into kinetic energy (of block)

 

Must see names of energy (gravitational potential energy and kinetic energy) – Allow for reasonable variations of terminology (eg energy of motion for KE).
