Learning Goal: To use the principle of linear impulse and momentum to relate a force on an object to the resulting velocity of the object at different times. The equation of motion for a particle of mass m can be written as ∑F=ma=mdvdt By rearranging the terms and integrating, this equation becomes the principle of linear impulse and momentum: ∑∫t2t1Fdt=m∫v2v1dv=mv2−mv1 For problem-solving purposes, this principle is often rewritten as mv1+∑∫t2t1Fdt=mv2 The integral ∫Fdt is called the linear impulse, I, and the vector mv is called the particle's linear momentum. A tennis racket hits a tennis ball with a force of F=at−bt2, where a = 1300 N/ms , b = 300 N/ms2 , and t is the time (in milliseconds). The ball is in contact with the racket for 2.90 ms . If the tennis ball has a mass of 59.7 g , what is the resulting velocity of the ball, v, after the ball is hit by the racket?
Learning Goal: To be able to use the conservation of energy on a moving body to determine key characteristics of the mechanics of the system. A package of mass m = 0.50 kg is pushed across the surface by a jet of compressed air during an assembly-line process. The package is moved through a distance of s = 50.0 cm. The package and the surface are known to have a coefficient of kinetic friction of μk = 0.15. The package is initially at rest for this process. PART A: If the package must be moving at a speed of v = 20.0 cm/s when it has reached the distance of 50.0 cm, determine the average force that the jet of compressed air must supply to the package PART B: If it is now desired that the package is at rest when it has reached the distance of 50.0 cm, determine the average force that the jet of compressed air must supply to the package if the package is initially traveling in the s direction at a velocity of v = 16.5 cm/s. PART C: If the plant has changed the mass of the package…

account_circle Science PhysicsQ&A LibraryA child’s toy consists of a m = 31 g monkey suspended from a spring of negligible mass and spring constant k. When the toy monkey is first hung on the spring and the system reaches equilibrium, the spring has stretched a distance of x = 17.6 cm, as shown in the diagram. This toy is so adorable you pull the monkey down an additional d = 7.6 cm from equilibrium and release it from rest, and smile with delight as it bounces playfully up and down. 1. Calculate the speed of the monkey, ve, in meters per second, as it passes through equilibrium. 2. Derive an expression for the total mechanical energy of the system as the monkey reaches the top of the motion, Etop, in terms of m, x, d, k, the maximum height above the bottom of the motion, hmax, and the variables available in the palette. 3. Calculate the maximum displacement, h, in centimeters, above the equilibrium position, that the monkey reaches. A child’s toy consists of a…
Learning Goal: To use equilibrium to calculate the plane state of stress in a rotated coordinate system. In general, the three-dimensional state of stress at a point requires six stress components to be fully described: three normal stresses and three shear stresses (Figure 1). When the external loadings are coplanar, however, the resulting internal stresses can be treated as plane stress and described using a simpler, two-dimensional analysis with just two normal stresses and one shear stress (Figure 2). The third normal stress and two other shear stresses are assumed to be zero. The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are given in one coordinate system (Figure 3), the equivalent stresses in a rotated coordinate system (Figure 4) can be calculated using the equations of static equilibrium. Both sets of stresses describe the same state of stress. The stresses σx′and τx′y′ can be found by considering the free-body…

You are tasked with designing the runway on an aircraft carrier. The minimum speed for the F/A-18 Hornet is 193.8 mph. The Hornet weighs 40,000 lbf and its twin engines provide a thrust of ~40,000 lbf combined, providing a max acceleration of 1g. How long must the deck be to takeoff unassisted in feet?

Let's begin by determining the equilibrium position of a seesaw pivot. You and a friend play on a seesaw. Your mass is 90 kg, and your friend’s mass is 60 kg. The seesaw board is 3.0 mm long and has negligible mass. Where should the pivot be placed so that the seesaw will balance when you sit on the left end and your friend sits on the right end? a)Let's look at the same scenario we just worked through, but instead, the board now has a non-zero mass of 15 kg. Where should the pivot be placed for balance?
