A car races at a constant speed of 25 m/s around a circular track with a radius of 150 meters. Consider 1/4 of a lap starting on the south side (heading east) and ending on the east side (heading north). A. How much time does the car take to travel between the two points? B. w...

The displisacement from A to B is 36 miles at 12 degress N of West. The displacement from B to C is 39 miles at 21 degrees N of E. What is the displacement from A to C by graphical means and by compnents?

A golf ball is dropped from rest from a height of 8.20 m. It hits the pavement, then bounces back up, rising just 5.40 m before falling back down again. A boy then catches the ball when it is 1.40 m above the pavement. Ignoring air resistance, calculate the total amount of tim...

Along a straight road through town, there are three speed-limit signs. They occur in the following order: 56 , 33 , and 24 mi/h, with the 33 -mi/h sign located midway between the other two. Obeying these speed limits, the smallest possible time tA that a driver can spend on th...

Thanks Much!

Compute the derivative for the following: n(x) = sin(x^3-5x^2+4x-7) Thanks, andy

If I figured out average velocity can I use that to figure instantaneous velocity? There is no function. Thanks

Well thanks again for the help...and I am probably older than you...hence the mind gaps of my own!

The question was 6-fold but the only part with the restriction was min and max values of y...everything else pertained to the original function.Thanks for staying with me...it's been a long day!
calculus
the original function was x^5-15x^3 +10 so when you figured the min and max with the restrictions and substituted 1, and 5 for the x's should you have included the constant 10? So I came up with (-4) and (1260), but forgive me I still don't know what that means...thes ...
