A box weighing 200N is pushed up an incline plane that is 2m long. A force of 1400N is required. If the box is lifted 1m calculate the percent efficiency of the inclined plane? Please help

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

In what direction does an applied force move an object

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?
