AI Thread Summary
To solve for the horizontal component of a force applied at an angle, the correct formula is F*cos(θ), where F is the force and θ is the angle from the horizontal. In this case, with a force of 82 N at 35 degrees below the horizontal, the horizontal component can be calculated using this formula. The vertical component would be found using F*sin(θ). Understanding these components is essential for analyzing forces in physics problems involving angles and vectors. Proper application of trigonometric functions is crucial for accurate calculations in such scenarios.

Homework Statement



It has been a while since I have taken pre-cal, thus I am not very good with trig. A man pushes a dolly with a force of 82 N which makes an angle of 35 degrees below the horizontal. Is the force along the x-axis F*sin(theta)? Or cos?

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.
