AI Thread Summary
The discussion centers on calculating the average acceleration of a flea after take-off, given its initial speed of 0.73 m/s and a take-off distance of 8.0 x 10^(-4) m. The user interprets the situation as starting from zero speed and accelerating to the final speed. To find the average acceleration, it is suggested to use the equations of motion, where the final speed is 0.73 m/s and the distance covered during acceleration is 8.0 x 10^(-4) m. By assuming constant acceleration, the user can solve the equations to determine the average acceleration. This approach clarifies the interpretation of the flea's motion during take-off.

Hello,
A flee jumps a horizontal distance of 0.035m with an angle of 70°.
I calculated the startspeed, v0, to 0.73m/s (projectile motion) - but then I am asked the following:
"What is the flee's average acceleration, if the startspeed is achieved after a take-off on 8.0 * 10^(-4) m"
How should i interpret the this situation?( As the startspeed being zero, and the flee accelerating to point where the speed, v0, is achieved? sounds odd to me)

If you assume a constant acceleration, a (the average acceleration), then the final speed is at= 0.73m/s and the distance is (1/2)at2= 8.0 x10-4m. Solve those two equations to find a.
 
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}...
