Question #1) A boy pulls a sled of mass 5.0 kg with a rope that makes an 60.0degree angle with respect to the horizontal surface of a frozen pond. The boy pulls on the rope with a force of 10.0 N; and the sled moves with constant velocity. What is the coefficient of friction between the sled and...
Can someone explain the following forces(equations, different ways to find them,
Tension Force
Frictional forces (static and Kinetic)
Normal Forces
I have a force labeled as Fp on a Diagram, if you know what that is could you tell me what it is and explain it.
(I was absent a few days...
Marlon, that doesn't seem right, I keep getting 675 and the answer says its 626 (multiple choice question, closest answer is 626, and teacher said answer is 626)
Thanx for everyone who has helped so far.
(This is not homework, I'm doing problems to study for my final that is in less than 3 hours).
This next question I'm having a hard time with is...
A 2150-kg truck is traveling along a straight,level road at a constant speed of 55.0km/h (15.8m/s)...
A quarter back throws a pass at an angle of 35degrees above the horizontal with an initial speed of 25 m/s. The ball is caught by the reciever 2.55 seconds later. Determine the distance the ball was thrown.
My answer: (25m/s * Cos(30)) * 2.55 s
Is it correct? My calculator just died and the...
ah, so since it takes one second to go up, another to go down... and its decelerating at 9.8 meters a second... it has to have enough acceleration to lose 9.8 meters going up, and 9.8 going down,
what does V_y mean?
alright. good now i understand something else.(My teacher is stupid and should keep teaching just normal high school physics and not try this stuff all he does is draw pictures of things from the problems and spends so much time makeing them look good we don't learn as much as we should.)...
So anytime an object is moving through the air without air resistance the only force of acceleration is gravity? and if air resistance is their, that is the only thing that will affect the acceleration?
A football is kicked at an angle (theta) with respect to the horizontal. Which one of the following statements best describes the acceleration of the football during this event if air resistance is neglected?
A) The acceleration is 0 m/s^2 at all times.
B)The acceleration is 9.8 m/s^2 at all...
well i didnt wana ask a question and have to wait till later to get the answer because id have to have it in the next 5 hours when I leave for school
ok the next post I make will have my question.
I need to know if anyone is up to answer more questions... They aren't very hard. Just questions from the first semester of an A.P Physics Course. If you are able to answer questions...pls respond to this and I will create a new thread for the questions and anyone else who needs the review can...
erg.. I hate this... No wonder I'm having a hard time in this class, I keep using the wrong equations. Thank you So much... These questions seem so easy.. I just haven't done any in a few months.
Alright now I have the right answer.
This is my last question for a about 20 minutes I have to...
oops... I just noticed i plugged in something wrong, thanks for help on that problem. and the vi^2 i had that written down but I was reading off my work not the equation, and since it is at rest vi = 0. Alright... Next Problem.. These aren't numbered by the worksheet I'm just writing down the...
I have finals at school tomorrow for A.P. Physics (college level physics)
I was wondering if someone could help me for a few minutes and I am just going to ask about a few questions at a time.
(These questions are multiple choice, and I have all the answers from the teacher but I need help...
