Question

A mass of 8 kg with initial velocity 18 m/s
travels through a wind tunnel that exerts a
constant force 5 N for a distance 0.5 m. It
climbs a frictional incline of height 2
clined at an angle 16
◦
, then moves along a
second frictional surface of coefficient 0.19 before coming to rest.
The acceleration of gravity is 9.8 m/s

If the first frictional surface has a coefficient
of 0.24 for a distance 0.8 m, how far does it
slide along the second frictional region before
coming to rest?
Answer in units of m
