... ANS: Here I would use Newton’s first law of motion. The plane is accelerating backwards when landing. The book indeed has inertia, so Newton’s first law suggests that the book would tend to remain in a constant state of motion, so it would tend to slip forward (relative to the plane), not backward. ...

... A. If you park on a hill with a 10 degree slope with the car held by the parking brake, what is the magnitude of the frictional force that holds your car in place? B. The coefficient of static friction between your car's wheels and the road when wet is 0.30. What is the largest angle slope on which ...

Two people of masses 60 kg and 80 kg leave the lift and nobody gets in. The lift with its four people inside then goes to t ...
