Apply Newton's second law to the bucket and find the maximum upward acceleration that can be given to the buck

Question

A bucket of water with mass 6.40 kg is accelerated upward by a cord of negligible mass whose breaking strength is 65.0 N .

Answer 1

net force = mass x acceleration

net force = tension of the cord - force of gravity

(The minus sign is because the tension is up and gravity is down)

You know the maximum tension on the cord, and the force of gravity on the bucket so you can determine the maximum net force.

With that and the mass of the bucket, you can determine the maximum upward acceleration

Answer 2

Sum of all forces on the mass = mass circumstances acceleration Sum forces interior the up direction with (+) being upward T + mg = ma T + 4.80(-9.80) = 4.80(a) sparkling up for a 80 two.0 - 40 seven.04 =4.80a 34.ninety six = 4.80a 7.28 = a gadgets are in meters according to 2d squared
