Here the kinetic energy of block will be lost in doing work against the friction force
Now Friction force = umg
Work done by friction= umgL
umgL = 1/2mv^2
u = v^2/2gL
So a is correct

1 (15 pts) A block of mass m 2.10 kg slides with an initial speed v 4.65 m/s on a frictionless, horizontal surface. The block now encounters a rough patch with a coefficient of kinetic fric- tion given by k-0.275. The rough patch extends for a distance d 1.20 m, after which the sur- face is again frictionless. (a) What is the acceleration of the block when it is in the rough patch? (b) What is the final speed vf...

Block A of mass mA is moving horizontally with speed Va along a frictionless surface
Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...
