Question A 75kg man jumpst from a window 1.0m above the side walk. a) What is his speed just before his feet strike the pavement? b) If the man jumps with his knees and ankles locked, the only cushion for his fall is approximately 0.50 cm in the pads of his feet. Calculate the average...

I would really appreciate it if you could help me out with this type of problem...I'm struggling a bit on the order of work that I need to do. Problem: The ball is fired from the ground with an initial speed of 1.70 x 10^3 m/s at an initial angle of 55 degrees to the horizontal. Neglecting...

DO NOT REPLY...I've already figured it out

Police Question... Question: A speeder passes a parked police car at 30.0 m/s. The police car starts from rest with a uniform acceleration of 2.44 m/s^2. a) How much time passes before the speeder is overtaken my the police car? Ans: 24.6 s b) How far does the speeder get before being...

Question: 54) A small fish is dropped by a pelican that is rising steadily at 0.50 m/s. a) After 2.5 s, what is the velocity of the fish? Ans: -24 m/s b) How far below the pelican is the fish after 2.5 s? Ans: 31m My Work/Question: The fish would be moving at the same velocity as...

The site that has helped me the most is the following link... http://www.regentsprep.org/regents/math/geometry/GCG6/RCir.htm

It is trig in a Calculus book...I should have put it into a different forum, sorry.

Find point of Equidistance... Find the point that is equidistant from (0,0) , (2,3) , and (3,-2)... I have plotted the points and have drawn a circle, putting all points on the outside...showing the equidistance. I plan on guesstimating a point int he middle, labeling it (X1,Y1)...then, I...

The answers in the book are... 0 , (pi/4) , pi , ((5pi)/(4))

Is there any way to show your work besides plugging in...as my teacher is a stickler for descriptive work?

I'm a little bit confused on this point... I plug tan(theta) back into (x-1)(x+0) ? Thus, making... tan(theta) = 1 and tan(theta) = 0

Am I on the right track here?

okay... x^2 - x = 0 (x-1)(x+0) = 0 x = 1 or x = 0

I don't have a calculator with me so I'll have to wait until school... The next question using same directions: tan^2(theta) - tan(theta) = 0

2sin^2 (theta) = 1 sin^2(theta) = 1/2 sin(theta) = sqrt(1/2 ? Those are my first few steps...are there any problems?
