Document Summary

Sixth series: questions on newton"s laws: a mother of mass 50 kg and her daughter of mass 25 kg are ice-skating. The weight of the crate is 296 n and the friction force between the crate and the surface is 90 n. what state of motion may the crate be: a man pushes a heavy crate. His push makes an angle of 30o with the horizontal, as shown. 50. 0(cid:32)k(cid:80: a ship is launched toward the water on a slipway making an angle of 5o with the horizontal direction. The coefficient of kinetic friction between the bottom of ship and the slipway is. The angle of the inclined is (cid:84) =15o. 1: a force of 300 n is applied to 70 kg carton on a level floor an angle 15o below horizontal. The coefficient of static friction between the carton and the floor is that of sliding friction is acting on the carton.
