A cyclist wants to carry a heavy bag of books on her bicycle, using a shopping bag hanging from the handlebars. When she attaches the bag, it swings from side to side with a period of 1.2 s. When she rides the bicycle, her body swings from side to side each time she turns the pedals. If the bag swings with the same period, it makes the bike wobble dangerously from side to side. The diameter of the back wheel is 650 mm. There are 15 teeth on the rear cog and 48 teeth on the chain ring. What speed on the road should the cyclist try to avoid?

A spring-based toy gun is used to shoot a ball of mass M straight up.The ball is not attached to the spring. The ball is pushed downward into the spring so that the spring is compressed toa distance S below its relaxation point. After the release, the ball reaches a maximum height 3S,measured from its relaxation position, see Fig. 1(b). (a) Find the constant of the spring. (b) Findthe equilibrium point of the ball when it is on the compressed spring with no forces other than gravity and thespring acting on it. Clearly indicate the point you are using as the origin of your coordinate system and which direction is positive.system and which direction is positive. (c) Now the ball is glued to the spring so that it oscillates up and downinstead of flying off the spring. The spring is again compressed to the same distance S below itsof relaxation. Write an equation for the position of the ball as a function of time after it is released. Indicateclearly which point you are using as the origin…
The spring-mounted 0.8 kg collar A oscillates along the horizontal rod, which is rotating at the constant rate q = 6 rad/sec. The spring constant k equals 5 N /m and the coefficient of kinetic friction mk equals 0.4. At a certain instant, r = 0.2 m, which is increasing at the rate of 800 mm/s, while r = 0.3 m / s2. For this instant, calculate the friction force from the rod onto the collar and the elastic force on the collar. Indicate whether or not the elastic force points towards the origin O and then calculate the spring stretch. (Hint: the total normal force between the rod and the collar results from both the weight of the collar and the transverse normal force that is perpendicular to the rod on the plane of rotation of the rod.)

A block of mass m= 2.0 kg is released from rest on an inclined plane at a height of h = 1.5 m. It moves down the rough incline with slope theta= 30.0°and continues on the horizontal frictionless surface. As shown in the figure, there is a spring with negligible mass and force constant k = 300 N/m. The coefficient of kinetic friction between the block and the incline is 0.250 What is the speed of the block when it gets down on the horizontal surface before it touches the spring? The box continues to move on the horizontal surface and compresses the spring. What will be the maximum compression of the spring?
(The complete question is in the picture) Consider a 2.0 [kg] box that is attached to two identical springs that are in their relaxed state when the block is centered on the frictionless horizontal floor.

If work done by the left spring is Wby spring = 25 [J], what is the speed of the boxas it passes the center x = 0? A. 8.2 [m/s]B. 7.1 [m/s]C. 3.5 [m/s]D. zero
The figure shows a pendulum bob that is moving in a vertical plane. At an angle theta 0° it has a velocity of 8m/s. The bob has a mass of 2kg, what is the tension in the rope holding the bob at its initial position and when it reaches an angle theta 30°? Neglect the size of the bob.
The conveyor belt shown below is inclined at an angle of 25 degrees. A 3kg package B is placed on the conveyor belt at the position shown with an initial velocity of 0 m/s with respect to the ground. The belt is moving quite fast, and as one could imagine the package is initially slipping, but it's accelerating at a rate of 3.05 m/s^2 until it catches up to the velocity of the belt. If this is the case, find the coefficient of friction between the belt and the package.
The block is released from rest at the position shown, figure 1. The coefficient of kinetic friction over length ab is 0.22, and over length bc is 0.16. Using the principle of work and energy, find the velocity with which the block passes position c.
