Answer 1 45 kj part b how much work is required to move it at constant speed 5 0 m vertically.
Two forces and are applied to the crate and it begins to move the coefficient of kinetic friction.
Determine the magnitude of the normal force that a the floor exerts on the crate and b the crate exerts on the person.
Number units number units.
Here s how to crack it the normal force on the object balances its weight so f n mg 100 kg 10 m s 2 1 000 n therefore f static friction max f f static max ยต s f n 0 4 1 000 n 400 n.
What is the minimum height where the force f can be applied so.
