Homework answers / question archive / The natural length of a spring is 10 cm
The natural length of a spring is 10 cm. A force of 25 N stretches it to a length of 20cm. How much work, in units of N-cm, is done in stretching it from a length of 10cm to a length of 15cm? Hooke's law for a spring is given by f=kx, where f is the force, x is the distance the spring is stretched, and k is a constant.
2. Find the slope of the tangent to the curve of y-in (25x+3) at x=2
I was waiting for your response for the correction required in problem 2. The equation given there is y - in (25x+3) which has to be y = ln (25x+3). The only closest possibility is that its 'ln' and not 'in'. I worked out the solution accordingly then.
