The force required to compress a non-standard spring as a function of displacement is given by the equationF(x) = -Asin(bx) + kx,where A = 25 N, b = 11 rad/m, and k = 68 N/m. Enter a general equation in terms of the given variables for the work required to compress this spring from position x1 to x2. Calculate the work done in joules as the spring is compressed from x = 0 to x1 = 21 cm. Calculate the work done in joules as the spring is compressed from x1 = 21 cm to x2 = 66 cm
A spring that obeys Hooke's law is hung in a vertical orientation. The spring is stretched a total of 6.0 cm from its equilibrium length when a 2.0 kg mass hangs from it. The spring, mass system is then pulled downward by an external force which lengthens the spring an additional 10cm. While the spring is being extended what is the work done by the spring?
Hard-working Len is forced to pull a 1000 [N] box located at the bottom of the inclined plane using a string with a force of 2000 [N] until it reaches the top of the inclined plane. The frictionless inclined plane has a surface length of 3.0 [m] and makes a 30° angle with respect to the ground. What is the total work done on the box?
The force required to compress a non-standard spring as a function of displacement is given by the equationF(x) = -Asin(bx) + kx,where A = 11 N, b = 11 rad/m, and k = 78 N/m. Part (b) Calculate the work done in joules as the spring is compressed from x = 0 to x1 = 32 cm. Part (c) Calculate the work done in joules as the spring is compressed from x1 = 32 cm to x2 = 69 cm
SQU is trying a new particle accelerator design with a mechanical component using a spring that does not obey Hooke's law. When stretched/compressed x metres, it exerts a force of 39.6x+51.6x2 (a) Compute the work required to stretch the spring from x= 1.0 m to x 1.3 m.
When a spring is compressed by 2.0 cm, its spring potential energy is 16.9 J. What will its spring potential energy be if it is stretched by 4.0 cm, in Joule? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
Problem 2: A certain spring has a spring constant k₁ = 660 N/m as the spring is stretched from x = 0 to x1 = 35 cm. The spring constant then changes to k₂ = 250 N/m as the spring is stretched to x2= 65 cm. From x₂= 65 cm to x3 = 89 cm the spring force is constant at F3 = 105 N.
A dart is loaded into a spring-loaded toy dart gun by pushing the spring in by a distance d. For the next loading, the spring is compressed a distance 2d. How much work is required to load the second dart compared to that required to load the first?
Indicate (with a T of F) whether the statement is true or false. If false, change the underlined word or phrase to make the statement true. A bicycle moving at 5.0 m/s at sea level has more potential energy than a motionless bicycle at the top of a mountain. Mechanical work is calculated by multiplying the magnitude of a force times the amount of time it is applied. The SI unit for work is the joule. One joule is equivalent to 1N: m in SI units 5 tv MacBook Pro
When a certain force is applied to an ideal spring, the spring stretches a distance x from its unstretched length and does work W. If instead twice the force is applied, what distance (in terms of x) does the spring stretch from its unstretched length, and how much work (in terms of W) is required to stretch it this distance?
