Waec Model Questions Vol1 2021 Physics Question 27
Practice objective / multiple choice question 27 from the 2021 Waec Model Questions Vol1 Physics examination.
A 5.0 kg block rests on a horizontal rough surface (coefficient of static friction \mu_s = 0.40, coefficient of kinetic friction \mu_k = 0.30). It is attached to a light string that passes over a frictionless pulley at the edge of the table and then to a hanging mass M. (a) Find the range of values of M for which the system remains at rest. (b) If M = 1.5 kg, determine the minimum horizontal force that must be applied to the 5.0 kg block in the direction of the tension so that the system just starts to move.
