Concrete Block Incline acceleration question

AI Thread Summary
A concrete block with a mass of 25kg on a 30-degree incline experiences gravitational force calculated as 245.25N. The component of this force acting down the slope is 122.625N, resulting in an acceleration of approximately 4.905 m/s². The discussion emphasizes the importance of drawing a free body diagram to visualize the forces acting on the block. Participants confirm the calculations but suggest further verification through proper diagramming. Accurate representation of forces is crucial for solving the problem correctly.

Homework Statement


A concrete block of mass 25kg is placed on a smooth slope that makes an angle of 30 degrees with the horizontal. Ignoring the effects of air resistance, calculate
a) the acceleration of the block as it slides down (g = 9.81 ms-2)
b) the distance the block moves in 3 seconds

Homework Equations

The Attempt at a Solution


w = mg
w = 25 * 9.81 = 245.25N
Wsin(theta) = 245.25 * sin(30) = 122.625N
122.625N / 25kg = 4.905ms-2?

whether it is correct or not will decide your 'free body diagram! pl. draw a free body diagram for the forces operating/acting on the block !
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

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}...
