Neco Model Questions Vol1 2017 Physics Question 7
Practice objective / multiple choice question 7 from the 2017 Neco Model Questions Vol1 Physics examination.
A light string of length \(1.00\ \text{m}\) passes over a frictionless, mass‑less pulley. A block of mass \(M\) hangs from one end, while a second block of mass \(m = 0.80\ \text{kg}\) rests on a horizontal table. The coefficient of kinetic friction between the block on the table and the table is \(\mu_k = 0.20\). When the system is released, the hanging block accelerates downward, and after the first \(0.50\ \text{s}\) the speed of the blocks is measured to be \(2.0\ \text{m s}^{-1}\). Determine the mass \(M\) of the hanging block (in kilograms, to three significant figures).
