19. A 19 g rifle bullet traveling 230 m/s buries itself in a 3.5 kg pendulum hanging on a 28 m long string, which makes the pendulum swing upward in an arc. Determine the horizontal component of the pendulum's displacement. m M UM=0 (a) M + m (b) C

Item 5 In this version of the "Giant Swing", the seat is connected to two cables, one of which is horizontal (Figure 1). The seat swings in a horizontal circle at a rate of 26.0 rpm (rev/min).

Sand moves without slipping at 6.0 m/sm/s down a conveyer that is tilted at 15∘∘. The sand enters a pipe hhh = 5.0 mm below the end of the conveyer belt, as shown in the figure (Figure 1).

In Fig. the upper ball is released from rest, collides with the stationary lower ball, and sticks to it. The strings are both 50.0 cm long. The upper ball has mass 2.00 kg, and it is initially 10.0 cm higher than the lower ball, which has mass 3.00 kg. Find the frequency and maximum angular displacement of the motion after the collision.

Can you please explain how to find the angle of theta in this problem? The answer states that it is 88.8 degrees but does not explain how. A propeller blade at rest starts to rotate from t = 0 s to t = 5.0 s with a tangential acceleration of the tip of the blade at 3.00m/s^2. The tip of the blade is 1.5 m from the axis of rotation. At t = 5.0 s, what is the total acceleration of the tip of the blade?

NOTE: The answer of 85.715 rpm was given to me and was incorrect. What is the correct answer?

A pendulum's angular position is given by ?= 0.0340 cos (?t), where ? is in radians and ? = 6.23 rad/s.  Find the period (in s) and length (in m) of the pendulum.

The smooth hollow tube assembly rotates about a vertical axis with angular velocity ω=θ˙=3.8ω⁢=θ˙=3.8 rad/s and ω˙=θ¨=−2.4ω˙=θ¨=-2.4 rad/s2. A small 0.23-kg slider P moves inside the horizontal tube portion under the control of the string which passes out the bottom of the assembly. If r=0.88r=0.88 m, r˙=−1.9r˙=-1.9 m/s, and r¨=3.8r¨=3.8 m/s2, determine the tension T in the string and the horizontal force Fθ exerted on the slider by the tube. T is positive in tension, and Fθ is positive if in the positive θ direction.

Write the vector expression for the acceleration a of the mass center G of the simple pendulum in both n-t and x-y coordinates for the instant when 0 = 54° if 0 = 2.06 rad/sec and 0= 4.395 rad/sec². Answers: a = (i a = ( i 2.7' C i+ i Me e) ft/sec² j) ft/sec² 3

4:48 O ll B/s docs.google.com/forms 11 225 J Consider a place where the gravity is 4 times the gravity on Earth (g' = 4g), then the frequency of oscillation of a simple pendulum in that place, f', as compared to its frequency on earth is: O f' = f/2 f' = 9f f' = f/3 O f' = 4f O f' = 2f A simple pendulum consists of a 0.8- kg bob connected to a massless inextensible cord with a length L = 1.1 m. The bob is set into motion and its angular displacement is given by e(t) = 0.11cos(wt), where e is in radians
