At the instant shown (t1 = 0), the position of the 2-kg object's center of mass is r = 5 (m) and its velocity is v = 5er + 3e? (m/s). A force of 100 (N) is applied to the object along the r-direction. What is the object's angular momentum about the origin O at t2 = 3 sec?

Step 1
The angular momentum of an object is given by the formula L = Iω, where I is the moment of inertia and ω is the angular velocity. Since the object is a point mass, its moment of inertia is zero. Therefore, the angular momentum at t=0 is also zero. Show more…

A particle of mass 5.0 kg has position vector $\overrightarrow{\mathbf{r}}=(2.0 \hat{\mathbf{i}}-3.0 \hat{\mathbf{j}}) \mathrm{m}$ at a particular instant of time when its velocity is $\overrightarrow{\mathbf{v}}=(3.0 \hat{\mathbf{i}}) \mathrm{m} / \mathrm{s}$ with respect to the origin. (a) What is the angular momentum of the particle? (b) If a force $\overrightarrow{\mathbf{F}}=5.0 \hat{\mathbf{j}} \mathrm{N}$ acts on the particle at this instant, what is the torque about the origin?
Angular Momentum A 2.0 kg particle-like object moves in a plane with velocity components $v_{x}=30 \mathrm{m} / \mathrm{s}$ and $v_{y}=60 \mathrm{m} / \mathrm{s}$ as it passes through the point with $(x, y)$ coordinates of $(3.0,-4.0) \mathrm{m} .$ Just then, in unit- vector notation, what is its angular momentum relative to (a) the origin and (b) the point located at $(-2.0,-2.0) \mathrm{m} ?$
A particle with a mass of $4 \mathrm{kg}$ has a position vector in meters given by $\mathbf{r}=3 t^{2} \mathbf{i}-2 t \mathbf{j}-3 \mathbf{k},$ where $t$ is the time in seconds. For $t=5$ s determine the angular momentum of the particle and the moment of all forces on the particle, both about the origin $O$ of coordinates.
