AI Thread Summary
To determine the horizontal force required to push a 70 kg crate up a frictionless ramp at a 23° angle, the calculations yield a horizontal force of 246.7 N and a normal force of 631 N. The net force is zero since the crate moves at constant speed, indicating no acceleration. A free body diagram was utilized to identify the forces acting on the crate. The discussion emphasizes the importance of writing equations for both parallel and perpendicular force components to solve the problem effectively. Understanding these force components is crucial for accurate calculations in physics problems involving inclined planes.

Homework Statement



A 70 kg crate is pushed at constant speed up the frictionless 23°

What horizontal force F is required? ( x Component Force)?

What force is exerted by the ramp on the crate?




Homework Equations



I used wsin(23) then i did (wsin(23))cos(23) which i found 246.73 N

and I used Wcos(23)= 631 N

I know that Fnet= 0 since the Velocity is constant acceleration is zero

I did a freebody Diagram



The Attempt at a Solution



I got 246.7 N for force in the Horizontal direction

and I got 631 N for what the second question is asking for.

I did that by calculating the Normal force.

Please Help

It's a bit hard to tell what you did. Start by identifying all the forces acting on the crate. Then write two equations: One for force components parallel to the incline; the other for components perpendicular.
 
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}...
