Concept explainers

Rigid Body

A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.

Rigid Body Dynamics

Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).

A small block of mass m is place on top of a hill as shown in the figure at the right, a height h above a horizontal track. The hill is frictionless, but when the block reaches the horizontal track, there is a
coefficient of friction, µ. The block slides along the track for a distance L and comes to a stop. For this motion air resistance can be ignored. We will take the origin of the coordinate system to be at A,
with x being the horizontal coordinate with positive to the right, and y being the vertical coordinate with positive up. We will choose our system to include the block, the hill, the surface with friction, and
the Earth. The parameters of the problem are those shown in the figure: m, g, µu, d1, L, dɔ, h, and 0. Also, the block has a speed vp at point B at the bottom of the hill.

A ball is suspended from a light 1.2 m string as shown. The string makes an angle of 27 degrees with the vertical. The ball is then kicked up and to the right such that the string remains taut the entire time the ball swings upwards. This kick gives the ball an initial velocity of 1.1 m/s. PART A. What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)? PART B: What will be the speed, in meters per second, of the ball when it reaches its lowest point (θ = 0)?

Figure 1: There is a rock here. The woman in the picture above is using the hunting weapon known as a sling. You might (or might not) have heard of this weapon in a story of David and Goliath. To use the sling, she puts a rock in a pocket at the end of a rope. She then twirls the rope in a circular motion over her head. When she is ready, she releases the rock and it flies away from her. The diagram below (Figure 2) shows the same situation schematically as it would be seen from above. Figure 2: View from overhead The rock is released here. Rope Rocki Woman In Figure 2, the rock is moving around a horizontal circle in a clockwise direction (as seen from above). When the woman is ready to throw the rock, she releases it from a point on the right-hand edge of the circle. After the rock is released (at the point indicated by the purple arrow and the words "the rock is released here"), it will most closely follow which of the dashed red paths shown below in Figure 3?

Water leaves a fireman’s hose (held near the ground) with an initial velocity v0 = 11.5 m/s at an angle θ = 30.5° above horizontal. Assume the water acts as a projectile that moves without air resistance. Use a Cartesian coordinate system with the origin at the hose nozzle position, as shown. 1). Using v0, θ, and g, write an expression for the time, tmax, the water travels to reach its maximum vertical height. 2)

A 1,040-N crate is being pushed across a level floor at a constant speed by a force F of 390 N at an angle of 20.0° below the horizontal, as shown in the figure a below. Two figures show a side view of a crate positioned upon a horizontal surface. Figure (a): An arrow pointing downward and to the right is labeled vector F and forms an angle of 20° below the horizontal as it approaches the upper left edge of the crate. Figure (b): An arrow pointing upward and to the right is labeled vector F and forms an angle of 20° above the horizontal as it extends from the upper right edge of the crate. (a) What is the coefficient of kinetic friction between the crate and the floor? (Enter your answer to at least three decimal places.)(b) If the 390-N force is instead pulling the block at an angle of 20.0° above the horizontal, as shown in the figure b, what will be the acceleration of the crate? Assume that the coefficient of friction is the same as that found in part (a).
A skier slides straight down an incline of 25 degrees without using her poles. The slope itself is 96 meters long, and the skier starts from rest at the top. What would the velocity of the skier be at the bottom of the incline if friction can be neglected? What would your answer be to the previous question if the coefficient of kinetic friction between the skis and the snow is 0.13 on the incline? Upon reaching the bottom of the incline in part b, she reaches a flat portion, and decides to just let friction slow her to a stop. How far does the skier travel along the horizontal portion before coming to a stop, if the coefficient of kinetic friction is 0.28 on the flat portion?
