The mouse wakes up and starts to walk north on the turntable, (i) As it takes its first steps, what is the direction of the mouse's displacement relative to the stationary ground below? (a) north (b) south (c) no displacement, (ii) In this process, the spot on the turntable where the mouse had been snoozing undergoes a displacement in what direction relative to the ground below? (a) north (b) south (c) no displacement. Answer yes or no for the following questions, (iii) In this process, is the mechanical energy of I lie mouse-i mutable system constant? (iv) Is the momentum of the system constant? (v) Is the angular momentum of the system constant?
Solution Summary: The author explains that the direction of the mouse's displacement relative to the stationary ground below is north because the turntable is at rest.

Definition Definition Product of the moment of inertia and angular velocity of the rotating body: (L) = Iω Angular momentum is a vector quantity, and it has both magnitude and direction. The magnitude of angular momentum is represented by the length of the vector, and the direction is the same as the direction of angular velocity.
If I am given a problem that provides the weight of a car and its inclination from the ground, how do i find the magnitude of the force against each tire?
Consider the two force vectors D = (2.64 N)i + (-5.6 N)j + (2.75 N)k and F = (2.11 N)i + (2.8 N)j + ak.
What should be the value of a, in units of N, so the two forces are perpendicular?
The resultant of the three parallelforces P, 2P and 3P, with theircorresponding locations, is denoted as R as shown in the figure.Determine the distance x and the magnitude of the resultant.
