Kinematics help?! How do I do this?
I've been trying this problem for forever and I can't get it! there are supposed to be 2 answers, 1 small and 1 larger... A rocket car is traveling at a constant speed of 250 km/h on a salt flat. The driver gives the car a reverse thrust, and the car experiences a continuous and constant deceleration of 8.25 m/s2. How much time elapses until the car is 175 m from the point where the reverse thrust is applied? (Hint: there are two answers.)
How do I do this Kinematics problem?
KE=.5mv^2 (kinetic energy), PE=mgh (potential energy) So you would use conservation of momentum equation: KE (initial) + PE (Initial)=KE (final) + PE (final) so you have: .5mv^2 +mgh= 0+0 solve for V, the mass cancels out and use building height for h, 9.8 for gravity hope that helps.
How do I finish kinematics in 1day?
Burn all classical mechanics textbooks, kill every person who knows even a little bit of kinematics and destroy all online resources which contain kinematics.Do this in a day and you will have answered your question.On the off chance, if you wanted to understand the whole of kinematics in a day then sorry, can't help you there pal. Kinematics is too vast.
How do I do this kinematics question?
Here is the procedure to solve the problem:Your answer.
How can I solve this kinematics question?
In second line, it will be time for object. Sorry :D
What are some tips for solving kinematics?
I am going to take a non-linear approach and just tell you how I follow suit:Kinematics deals with motion of objects without reference to the cause of the motion. So I suggest you do not start making force-body diagrams straight away.Its a good practice (and indeed standard) to split the motion into components along axes. Axes are defined by the coordinate system you are using. I suggest the Cartesian system for most problem types.Please take care of two things: Vectors and units. Directions are just as important as magnitude.If you are trying to solve a problem, try to list out whatever is given to you beforehand. Then try to apply a principle/relation that connects these parameters and also returns what you require. Of course, this is the tricky part. A good way to ensure that this works well is to divide each problem into smaller sub-problems.Look at question.Try to solve it.Try again.Ask for help.-------------Profit(?)Practice more questions.
I have no idea on how to do kinematics and need help.?
Here is one of the questions. A child riding a bicycle at 15 meters per second decelerates at the rate of 3 meters per second^2 for 4.0 seconds. What is the child's speed at the end of the 4 seconds. please help I am really confused on where to plug in the numbers and what equations to use when.
Kinematic and Newton's Forces, how do i do this?
The force Fon a student of mass M caused by a student of mass m a distance d away is: F = GMm / d^2 where G is the gravitational constant 6.67 * 10^(-11) N m^2 / kg^2. F = 6.67 * 10^(-11) * 79.5 * 60.0 / 2.25^2 = 6.28 * 10^(-8) N. Answer (e).
