AI Thread Summary
To calculate the work done when a 1150 kg car accelerates from 2 m/s to 6 m/s, the change in kinetic energy (KE) is used. The formula for work done is Work = 0.5 * mass * (final velocity^2 - initial velocity^2). Applying the values, Work = 0.5 * 1150 * (6^2 - 2^2) results in the total work done. The initial confusion about insufficient information was resolved with this calculation approach. Understanding the relationship between work and kinetic energy is crucial for solving similar problems.

I have no idea. It seems like insufficient information to me. Please help! I am in great need as my exam is drawing near!

Thanks!

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

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.
