What Is The Value Of The Derivative For The Given F(T)=(2t-5)(3t+4), When T=1/2

What is the value of the derivative for the given f(t)=(2t-5)(3t+4), when t=1/2

 

f(t)=(2t-5)(3t+4), when t= 1/2

Solution:

f(1/2)=(2 1/2-5)(3 1/2+4)

f1/2=(2.5-5)(3.5-4)

*converted it to decimal

f1/2=(-2.5)(-0.5)

f1/2=1.25

f 0.5=1.25

f 0.5=1.25

----- ------

0.5 0.5

f=2.5

A Force Of 500 N On An Object Of 2 Kg Displaces It By 3 M. Find The Work Done By The Force And The Objects Final Speed Assuming It Was Initially At Re

a force of 500 N on an object of 2 kg displaces it by 3 m. find the work done by the force and the objects final speed assuming it was initially at rest.   GIVEN: F = 500 N m = 2 kg d = 3 m FORMULA: W = Fd where: W = Work, J, kg•m•m/s•s F = Force, N, kg•m/s•s d = distance, m EQUATION: W = Fd F = ma SOLUTION: W = Fd W = (500 N)(3 m) W = (500 )(3 m) W = 1500 W = 1500 J ANSWER: The work done by the force is 1500 J. (NOTE: Im sorry. I do not how to get the final speed. I can only get the acceleration.)
