The 56.28 kg crate is hoisted up the 0 = 27° incline by
the pulley system and motor M. If the crate starts from
rest and, by constant acceleration, attains a speed of
8.17 m/s after traveling 7.84 m along the plane,
determine the supplied power to the motor if the crate
has moved 8 m and the coefficient of kinetic friction
between the plane and the crate is Hk = 0.3. Neglect
friction along the plane. The motor has an efficiency
of 0.691.

The cars of an amusement park ride have a speed va = 17 m/s at A and a speed vg = 10 m/s at B. If a 87-kg rider sits on a spring scale
(which registers the normal force exerted on it), determine the scale readings as the car passes points A and B. Assume that the
person's arms and legs do not support appreciable force.
