I with this question on velocity/displacement

AI Thread Summary
The discussion focuses on understanding the difference between speed and velocity in a physics context. The original poster calculated speed as 1.05 meters per second and identified the distance from point A to C as 316 meters but struggles with determining velocity due to uncertainty about displacement. Clarification is provided that displacement is essentially distance in a specific direction, represented as a vector from A to C. The importance of knowing both the length and direction of the displacement vector is emphasized for calculating velocity. Understanding vectors is suggested as a key concept that could simplify the problem.

Homework Equations



velocity = displacement / time taken

The Attempt at a Solution



I found out the answer to speed but not velocity because I honestly do not know how to do it.

The answer to speed is 1.05 meters per second. and the distance from a - c is 316meters.------

Help would greatly appreciated since this is due tomorrow morning. If you need any more information or need me to be clearer, please let me know.

Velocity is a speed in a particular direction. You just need to specify the direction. For example, how many degrees north of east?
 
But I'm not sure what or how to figure out displacement. If the equation to velocity is "velocity = displacement/time taken" then I'll need to know the displacement to answer the question.

Thanks.
 
Think of displacement as distance in a particular direction. In your problem, the displacement vector would be depicted as an arrow going from A to C. You already know its length; all you need is its direction.
 
Question: Have you ever worked with Vectors before? Because that would render this entire exercise rather trivial.
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
