A spring is attached to an inclined plane as shown in the figure. A block of mass m is placed on the incline, a distance d along the incline from the end of the spring. The block is given a quick tap, giving it an initial speed v, and it slides freely down the incline until it hits the spring. The incline angle is θ, the spring constant is k, and we can assume the surface is frictionless. By what distance is the spring compressed when the block momentarily comes to rest? (Use any variable or symbol stated above along with the following as necessary: g.)
A block of mass 0.5 kg is initially resting against the spring, compressing the spring at a distance of 15 cm. If the spring constant is 400 N/m, what is the distance the block travels on the incline when it momentarily comes to rest? Consider the horizontal surface and the incline as frictionless surfaces. 0.5kg 30.0°
of k = 700 N/m. A block of mass m = 1.10 kg is attached to the spring and rests on a frictionless, horizontal surface as in the figure below. The left end of a horizontal spring is attached to a vertical wall, and the right end is attached to a block of mass m. The spring has force constant k. Three positions are labeled along the spring, and the block is pulled to the rightmost position, stretching the spring. The leftmost position, the equilibrium position, is labeled x = 0. The middle position, halfway between the leftmost and rightmost positions, is labeled x = xi⁄2. The rightmost position is labeled x = xi. (a) The block is pulled to a position xi = 6.80 cm from equilibrium and released. Find the potential energy stored in the spring when the block is 6.80 cm from equilibrium. J(b) Find the speed of the block as it passes through the equilibrium position. m/s(c) What is the speed of the block when it is at a position xi/2 = 3.40 cm? m/s
The spring connects two objects. In this case, it's the object that moves and accelerates, and the wall. I will take x to be the distance from the particle to the wall -- the length of the spring. The problem is one-dimensional. (There are two- and three-dimensional forms of the problem.) The ideal spring exerts a force (F) on the object, with the following properties: The spring has a length (ℓ) where it exerts no force. (I usually call it the relaxed length. I might call it the "zero-force length" or the "equilibrium length".) The compressed spring pushes. The stretched string pulls. The force on the block is F = -k(x - ℓ). (Figure out what the negative sign on k does.) Often, people use x for the difference from equilibrium, and write F = -kx instead. Sometimes, both sides of the spring are at different positions. The force on the object on the right side is -k(x2 - x1 - ℓ). In the pictured situation, x1 = 0 and x2 = x. Understand what is physically happening with…
An orange block of mass 2.5 kg is on an inclined plane. There is no friction between the block and the plane except in the region shown in red and black on the diagram above. The plane is inclined at an angle of θ = 17 degrees above horizontal. The block begins at rest, leaning against a spring with a spring constant of k = 741 newtons per meter. At the start, the spring has a compressed length of x1 = 0.39 meters. The spring then expands to its equilibrium length of x2 = 0.65 meters, sending the block sliding up the ramp. The block has no friction with the plane except in the single region of length L = 0.78 meters, shown in red and black above. The coefficient of kinetic friction between the block and this region is μ K = 0.24. The block slides past this region and continues up the plane. What is the speed of the block, in units of meters per second, when it has slid a distance d = 1.3 meters along the plane from the place where it started? (This is the distance measured from the…
To form a pendulum, a 0.092 kg ball is attached to one end of a rod of length 0.84 m and negligible mass, and the other end of the rod is mounted on a pivot. The rod is rotated until it is straight up, and then it is released from rest so that it swings down around the pivot. When the ball reaches its lowest point, what are (a) its speed and (b) the tension in the rod? Next, the rod is rotated until it is horizontal, and then it is again released from rest.

The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists have studied the change in length of the knee extensor tendon in sprinters and nonathletes. They find (on average) that the sprinters’ tendons stretch 41 mm, while nonathletes’ stretch only 33 mm. The spring constant for the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes?
