Thank you. I realize my error now :)

Okay, so here are the two functions, f(x)= sqrt(x+3) and g(x) = (x+3)/2 my first step was to get the intersection points and it came out to be x=1 or -3 Then I drew a graph and that told me that the function sqrt(x+3) is always above the other function on the entire interval. So then I did...

thanks, yes it was downhill :)

thanks!

Question says. Two objects of mass 2kg each are attached to each other by a massless string. One moves vertically and the other is moving on a frictionless surface horizontally and is being pulled the opposite direction by a force of 10 N at 60 degrees to the horizontal get the acceleration of...

Okay so their are two objects attached together by a massless string and a frictionless pulley. One of them is hanging vertically with mass 5kg the other one is on an incline that makes a 30 degrees angle with the horizontal and is of mass 10 the coefficient of kinetic friction of the incline on...

Homework Statement a man throws a stone vertically upward with initial speed of 20 m/s from a building with height 54 m a)how long does the stone take to reach 40 m/s b)what is its velocity before it reaches the ground c) what is the magnitude of its acceleration at its maximum height...

just a silly typo sorry

thank you!

Homework Statement a motorist drives south at 20 m/s for 3 min, then turns west and travels west at 25m/s for 2 min, and finally travels n/w at 30 m/s for 1 min. for this 6 minute trip, find the net vector displacement Homework Equations The Attempt at a Solution distance 1...

it was on radians! Thank you! I got the right answer!

oops sorry!

When the Sun is directly overhead, a hawk dives toward the ground with a constant velocity of 4.15 m/s at 54.5° below the horizontal. Calculate the speed of her shadow on the level ground.Homework Statement Homework Equations vxi=vicosθ vyi=visinθ (i think) The Attempt at a Solution...
