A(n) 856 N crate is being pushed across a level floor by a force of 385 N at an angle
of 22◦ above the horizontal. The coefficient
of kinetic friction between the crate and the
floor is 0.17. The acceleration of gravity is 9.81 m/s^2

What is the magnitude of the acceleration
of the box? Answer in units of m/s^2

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
