18.998403 u
Hope this helps Have a good day
Answer:
part 1. 1/2kx^2 = 1/2mv^2
1/2(850)(0.40)^2 = 1/2(0.5)v^2
68 = 0.25v^2
272 = v^2
v = 15.49m/s
Explanation:
part 1. the max potential energy would be equal to the maximum kinetic energy assuming no energy is lost, because of this, we can set the spring potential energy to the kinetic energy. from there plug in all the variables sorry all known variables and solve for v. make sure to plug in 0.5 for mass so that it is in kilograms.
The speed and acceleration of the stone is 15.7 m/s and 31.4 .
<h3>What is acceleration?</h3>
Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration.
<h3>Calculation of the speed of stone lodged in the tread of the tire:</h3>
Given, radius of tire (r) = 0.500 m
<h3 />
= 15.7 m/s
<h3>Calculation of it's acceleration:</h3>
= 31.4 inward
Hence, the speed and acceleration of the stone is 15.7 m/s and 31.4

The metal's ability to conduct heat and become an evenly heated surface relatively quickly makes it useful for ironing. An uneven heat distribution is more likely to produce hot and cold patches, resulting in burnt clothes. Moreover, if the metal didn't conduct electricity well, the heating element would have to use more energy to produce the same amount of heat in the iron.
