** 12. A girl pushes horizontally cient of kinetic friction between the crate and the floor is 0.2; the coefficient of static friction is 0.4. on a 100-kg crate, as shown in the two figures below. The coeffi- a) For each of the two situations described in the figures, indicate whether the frictional force is static or kinetic. b) In each case, find the magnitude of the frictional force. Case 1: The girl is pushing with a force of 300 N, and the crate does not move. Case 2: The girl is pushing with a force of 300 N, and the crate is moving along the floor.
