When a net force of 3 N is applied to a 0 75 kg cart the cart's velocity changes from 0.2 m/s to 18 m/s in 0.3s Suppose that by adding masses the total mass of the cart doubles the same force applied for the same amount of time what will the change in velocity be in m/s? plz help no links or bad answers I’m in a test;(

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the
