A force of 4.0 N applied to a spring compresses it by 8.0 cm. What is...
How much work must be done to A) compress a spring 4.0 cm if the spring constant is 55 N/m? B) stretch a spring 8.0 cm if the spring constant is 85 N/m?
I) Spring, work with variable force: An applied force along the x-axis compresses a spring with stiffness constant 8000 N/m. a) Accurately graph the applied force F b) c) vs. x for this spring, with values from x = 0 to 0.50 m on the x-axis. By calculating areas directly from the graph, determine the work done by the applied force in compressing the spring from (i) 0 to 0.25 m. and from (ii) 0.25 m to 0.50 m. Do...
A forensic scientist calibrating a spring finds that if a force of 0.750 N is applied the spring, it will compress a distance of 0.250 cm. The same spring is then used in a ballistics experiment: a rifle bullet of mass 8.00 g collides with and embeds itself in a block of mass 0.992 kg that was initially at rest on a horizontal frictionless surface. The block is attached to the spring as shown. The impact compresses the spring 15.0...
A spring with a spring constant of 49 N/m is initially compressed by 7.2 cm. How much work is required to compress the spring an additional 5.0 cm?
9) An 8.0-9 bullet is shot into a 4.0-kg block, at rest on a frictionless horizontal surface (see the figure). The bullet remains lodged in the block. The block moves into an ideal massless spring and compresses it by 8.7 cm. The spring constant of the spring is 2400 N/m. (a) Determine the work done by the spring (b) Determine the initial velocity of the bullet before it strikes the block. for part b, just find the velocity of the...
A student exerts a force of 12 N to compress a spring of 2.54 cm. What is the force constant for the spring?
Question 15 A spring required a force of 5.0 N to compress it 0.1 m. How much work is required to stretch the spring 0.4 m? Hint: Work done is equal to the change in elastic potential energy 0.8) O 0.4) 2) 0.2
When a 57 kg cheerleader stands on a vertical spring, the spring compresses by 5.5 cm. when a second cheerleader stands on the shoulders of the first, the spring compresses an additional 4.5 cm. What is the mass of the second cheerleader?
If it requires 8.0 J of work to stretch a particular spring by 2.0 cm from its equilibrium length, how much more work will be required to stretch it an additional 4.0 cm?
If it requires 8.0 J of work to stretch a particular spring by 2.0 cm from its equilibrium length, how much more work will be required to stretch it an additional 4.0 cm? W=
