Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

The correct final answer is 2.87E-6. Please show how it became like that. A bullet of mass m=0.500 [g] is fired horizontally with a speed v=10.0 [m/s] into the bob of a ballistic pendulum of mass mP=0.500 [g]. Find the maximum height ℎ attained by the bob if the bullet passes through the bob and emerges with speed v/4.
FI R %24 Part A A ball of mass m moving with velocity v strikes a vertical wall as shown in (Eigure 1). The angle between the ball's initial velocity vector and the wall is 6 as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is At, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the force exerted on the ball by the wall is parallel to the x axis. What is the final angle Or that the ball's velocity vector makes with the negative y axis?

The sphere of mass m1 = 5 kg falls from a height H = 1.4 m onto the homogeneous board of negligible mass. The board can rotate around a horizontal axis passing through point O, and a body of mass m2 = 3.9 kg is placed on it at a distance b = 1 m from the axis of rotation. The collision is perfectly inelastic. How high does the body of mass m2 rise after the collision (in m) if a = 0.5 m?
Two balls (which we will label ball 1 and ball 2) undergo a perfectly elastic head-on collision, with ball 2 initially at rest. Suppose the incoming ball (ball 1) has a speed of 200 m/s. Assume all motion is one-dimensional and ignore friction and drag. (a.) Write out algebraic expression for both the Law of Conservation of Momentum and the Law of Conservation of Energy as they apply for this isolated system. (That is, for this part of the problem I want you to write the Conservation of Momentum equation and the Conservation of Energy equation for this system and plug in any known zero values but do not plug in any other numbers.) For the moment, leave the masses of the balls (m1 and m2) as algebraic variables (as I am not giving you numerical values for the masses just yet). (b.) We want to compute the final speeds (v1f and v2f) and directions (±x-direction, since the motion is assumed to be 1 dimensional) of the balls. We could use our conservation laws from part (a.) together to…
You want to speed up the system of rotating disks. To do this, you throw a ball of mass mb at the two disks that are still rotating together with the same speed (just after they collide). You throw the ball at the disks, and the ball follows the following trajectory as viewed from above. The ball of mass mb approaches the disks at an angle θ with respect to the tangent line to the disk and rebounds at an angle ϕ with respect to the normal. The ball's initial speed is v_0, and its final speed is v_f. What is the new z-component of the angular velocity of the system of rotating disks (they still rotate together) after the collision with the ball? Use these values for the parameters (associated with image 1): v_f=2.13 m/s v_0=14.2 m/s θ=63.2∘ ϕ=68.7∘ m_b=1.59 kg R=2.68 m *Initial scenario if it helps* Two disks are initially spinning, one above the other on a small axle that provides a small, but non-negligible torque from friction, as shown in the figure below.
