1. ## AP PHYSICS MECH.

A simple pendulum, consists of an object suspended by a string. The object is assumed to be a particle. The string, with its top end fixed, has negligible mass and does not stretch. In the absence of air friction, the system oscillates by swinging back and

2. ## physics

A 73 kg crate is dragged across a floor by pulling on a rope attached to the crate and inclined 15° above the horizontal. (a) If the coefficient of static friction is 0.52, what minimum force magnitude is required from the rope to start the crate moving?

3. ## AP PHYSICS MECH.

Need help urgent!!! A system consist of a ball of M2 and a uniform rod of M1 and length d. The rod is attached to a horizontal frictionless rotates at an angular speed w, as shown in the figure. The rotational inertia of the rod about point P is ? M1 d^2.

4. ## AP PHYSICS MECH.

A 5.00 g bullet moving at 648 m/s strikes a 670 g wooden block at rest on a frictionless surface. The bullet emerges, traveling in the same direction with its speed reduced to 440 m/s. A 5.00 g bullet moving at 648 m/s strikes a 670 g wooden block at rest

5. ## AP PHYSICS MECH.

In Figure 9-62, block 2 (mass 1.3 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 160 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 2.1 kg), traveling at speed v1 = 4.0 m/s,

6. ## math calculus

In the viewing rectangle [-4, 4] by [-20, 20], graph the function f(x) = x3 - 3x and its secant line through the points (-3, -18) and (3, 18). Find the values of the numbers c that satisfy the conclusion of the Mean Value Theorem for the interval [-3, 3].
