A cylindrical pulley with a mass of 7.9 kg, radius of 0.829 m and moment of inertia 1/2M r2 is used to lower a bucket with a mass of 3.3 kg into a well. The bucket starts from rest and falls for 4.2 s.What is the linear acceleration of the falling bucket? The acceleration of gravity is 9.8 m/s2 .
Answer in units of m/s2.
At t1 = 0.87 s, find the magnitude of the total acceleration of the point.
Answer in units of m/s2.
