a rope of negligible mass supports a block that weighs 30 n, as shown above. the breaking strength of the rope is 50 n. the largest acceleration that can be given to the block by pulling up on it with the rope without breaking the rope is most nearly

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
