I know V is Velocity, A is Acceleration and T is time. What is U? I've never seen it.

I'm wrong on C, it has to be: 25 m/s (Cos 65)(2.40 m) I still don't get B. Gregg, isn't that how I solve for Initial velocity?

But it's asking for the velocity @ 2.40 seconds. Don't you break up vectors into components?

Homework Statement Using the appropriate kinematic equations and initial values, determine the position and velocity at t=2.40 s. (x, y)=0, 0 (vi, 0)=(25.0 m/s, 65.0 degree) a.Horizontal Velocity of the initial velocity b.Horizontal/Vertical Velocity at 2.40 s c.Horizontal...

If the wind is blowing from the west doesn't that mean it's going east? Thus positive? acrCos(.75) What does this mean? Thank you.

Homework Statement An aircraft has a cruising speed of 100 m/s. On this particular day, a wind is blowing from the west at 75 m/s. If the pilot wishes to have a resultant direction of due north, in what direction should the plane be pointed? What will be the plane displacement in 1.25 h...

A. T=D/S =50 m/2m/s =25 seconds B. C2=A2+B2 Is that correct? It's a right angle triangle...... . . . . . Up is 2 m/s and sideways is 3 m/s. The resultant would be the hypotenuse correct? How would I go about getting C?

The component of the displacement? I'm so lost lol... can you run that by me again please? Is it like this? ------>---------> 2 m/s 3 m/s Those are the two vectors no?

I'm confused as how to calculate displacement for this, can you give me an example please?

Homework Statement A man walked 440 m 50 degrees polar positive, and then 580 m 185 degrees polar positive. The entire trip took 150 min. Total distance travelled? The displacement of the man? Average of the man in m/min? Average velocity of the man in m/min? Homework Equations...

Time=Displacement/Velocity?! How do you know the dog is it an angle? I thought the dog was facing the stream

Homework Statement A dog wishes to swim across a slow-moving stream. The dog can swim at 2 m/s in calm water. The current velocity is 3 m/s. The distance directly across the stream is 50 m. If the dog points himself directly across the stream how long will it take to get across the...

Oh! I get it. Thank you very much. I'm trying to graph a Position-Time graph, Velocity-Time graph, and Acceleration-Time graph but am stuck. I get what the question is asking me but aren't all graphs going to look exactly the same minus what I name the x and y axis? Here's the Q: You are...

Homework Statement A balls roll along a straight path with the following velocity and time intervals 3.0 s at +15.0 m/s 7.0 s at +20 m/s 6.0 s at -30 m/s 4.0 s at 3.5 m/s What is the displacement in the last 5.0-15.0 time interval: I've been looking at this question for a good 30...

If velocity is the change in position per unit time and acceleration measures the change in velocity of an object, can an object zero velocity or zero acceleration? In terms of a baseball, the baseball stands still for a moment at the top. Would that mean it has zero velocity? But does a...
