Hot commity ,, u are a genius, it seemed that i wasn't converting the distance from kilometers to meters. It was right in front of me all along, Thanks for the help all, i really appreciate it ... another thing that's bothering me is this question: A student a compressed spring of force...

A 1200kg space probe traveling initially at a speed of 9500 m/s through deep space fires its engines that produce a force of magnitude 92000N over 86 km distance. Determine the final speed of the probe. Attempt at solution: I tried finding the acceleration by dividing the mass by the force...

Tycoo4, i have the total horizontal distance, its 1.4 meters from the launch site which is .95 meters on a bench. I have the launch angle and it's 45 degrees, also i have the constant of the spring at 40n/m. The mass of the spring is 50 g. Thats why I am thinking about the conservation of energy...

One other question, does it help if I am using the conservation of energy thereom of Ee=Ek+Eg .5kx^2=.5mv^2+mgh. Tell me if I am heading in the right direction

Is there a way you can show me this ...im not sure how you're suppose to start...I know that take off is definitely at .95 m and landing is actually .95 meters down to the floor. Mass of the spring if it helps is actually 50g. How do you figure out time is my major dilemma here. Thanks

Just one question that plagues me is what you do when you initially launch from a bench and the target is on the floor. I have an angle of 45 degrees as my launch angle. Another confusion is which velocity is being used , initial or final. If initial would it look like vcos45 and vsin45. And...

Thanks but Thats exactly it, that's the part that i seem to be having trouble with. Finding that simple projectile equation. I need to know the equation to sub in all the information such as height and angle of inclination in order to get the change in x

any help will be appreciated i know you have to work with the equation y=vt+1/2at^2 but I'm not sure to what degree if any.

Launching spring at targets (physics)? I have a question regarding physics. Its about launching a spring at various targets (bucket) at different distances and heights. What is the equation to find the amount of stretch from equilibrium (in the string) i.e. x. We are given the vertical...
