A 0.580-kg bucket rests on a scale. Into this bucket you pour sand at the constant rate of 85.0 g/s.
A)If the sand lands in the bucket with a speed of 4.30 m/s, what is the reading of the scale when there is 0.770 kg of sand in the bucket?
B)What is the weight of the bucket and the 0.770 kg of sand?
