Homework for Lab 15: Simple Harmonic Motion Name Date Section 15 10 -5 -15-10-5 0 5 10 15 Displacement (em) Figure 15.6: Force vs displacement graph for a 0.75 kg cart on a horizontal spring. 1. Figure 15.6 shows the force exerted by the spring on a 0.75 kg cart, as a function of its displacement from equilibrium. Positive displacements (in cm) represent stretching of the spring; negative displacements represent compression. Find the spring constant. 2. The cart is moved...
A spring has a force constant k=500 N/m. What is the elastic potential energy stored in it when (a) it is stretched 4.00 cm from equilibrium, (b) it is compressed 3.00 cm from equilibrium, and (c) it is unstretched?
In the figure below, a 4.0 kg block is accelerated from rest by a compressed spring of spring constant 600 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction uk= 0.30.The frictional force stops the block in the distance of D = 8.0 m. -- No friction a) Find the increase in the thermal energy of the block-floor system b) What is the original compression...

In the figure, a 3.9 kg block is accelerated from rest by a compressed spring of spring constant 630 N/m. The block leaves the spring at the spring's relaxed length and travels over a horizontal floor with a coefficient of kinetic friction mu_k = 0.215. The frictional force stops the block in distance D = 7.7 m. What are (a) the increase in the thermal energy of the...

+ 0 A cart attached to a spring is given an initial push, Displacement, cm displacing it from its 4 A B equilibrium position. A 2 graph of displacement as a ус function of time for the 2 cart is shown at right. The -2-1 system has a total initial energy of 12 J and there is no friction.

Experiment: The force required to stretch an elastic is measured, along with the displacement of the elastic. The elastic is then used to launch a cart on a low friction track and the motion of the cart is analyzed. The experiment is repeated for a total of 5 trials. I need to draw a graph of kinetic energy of cart as a function of energy transferred to elastic. The energy transferred to elastic is elastic potential energy, given by E=1/2Fx....
