Take g E9.81 m/s2. Number A o Previous 2 Check Answer 0 Next Exit

Explanation / Answer

Initial Energy,E = PE + KE

= M*9.81m/s^2*1. 25 + 1/2*M*(1.69m/s)^2

= M*12.26m^2/s^2 + 1.428m^2/s^2 = M*13.69m^2/s^2

Friction work done = M*13.69m^2/s^2 = umgd

where,u is coefficient of kinetic friction

umgd = M*13.69m^2/s^2

0.267*M*9.81m/s^2*d = M*13.69m^2/s^2

d = 5.226m
