wow I read some more and change in jounce is called crackle and change in crackle is called pop? (on the jounce wikipedia page) I really want to learn more about these lol. What if you integrated position? What happens then?

Hello, I was doing some research on differentiating kinematics. For example, differentiating displacement will give you velocity, and differentiating velocity gives you acceleration. When you differentiate acceleration apparently you get something called "jerk" (wow what a jerk). And when you...

i meant .5apt^2 and .5ast^2

p=police s=speeder so would i do this? vopt+\frac{1}{2}apt=vost+\frac{1}{2}ast because the time will be the same, right? and then i use the "t" time and find the displacement?

so i should use x=vot+0.5at^2?

A speeder passes a parked police car at 30.0 m/s. The police car starts from rest with a uniform acceleration of 2.60 m/s2. (a) How much time passes before the police car reaches the speeder? (b) How far does the speeder get before being overtaken by the police car? Relevant...

1. An elevator cab in the New York Marriott Marquis has a mass of 4.15 x 103 kg and can carry a maximum load of 1.80 x 103 kg. If the cab is moving upward at full load at 3.57 m/s, what power is required of the force moving the cab to maintain that in kilowatts?W=Work P=Power t=Time F=Force...

oh and thanks for c). i got it right.

well ok, i did 2.4(9.8)(-1). that gives me -23.52. it still tells me I'm wrong :confused:

@vespa71 the problem said the ceiling to the floor was 3m

so will a) be negative because 2-3=-1? therefore, will the answer be -23.52? and will c) be zero because 2-2=0 and 2.4(9.8)(0)=0?

ok, so I did 2.4(9.8)(1)=23.52 for a). i still get it wrong... and for c), do i just do 2.4(9.8)(2) because it's the inverse?

Homework Statement A 2.40 kg ball is attached to a ceiling by a 2.00 m long string. The height of the room is 3 m. What is the gravitational potential energy of the ball relative to: a) the ceiling? b) the floor? c) a point at the same elevation as the ball? Variables P for potential...

Ok thanks.

and that means Fp=76.44 N..right? Because the ax cancels out and 30(0)=0.
