What is Mathematics Paper 4 Mechanics 2023 about?
A particle is projected vertically upwards from the ground with an unknown initial speed u. The height of the particle above the ground is given at times 3 seconds and 4 seconds after projection. The question asks to find the value of u and the value of s. A hammerhead of mass 1.2 kg drops vertically onto a nail of mass 0.004 kg. The hammerhead hits the nail with an initial speed v and they remain in contact after impact, moving with a combined speed of 40 m/s. The question asks to calculate the value of
