AI Thread Summary
To find the initial velocity of a body thrown up a slope, the problem states it reaches a point at two different times, t1 = 1 sec and t2 = 2 sec. The equations of motion provided are s = ut + (at^2)/2 and v = u + at, which can be used to analyze the motion. The challenge lies in determining the initial velocity and the position at t = 1.5 seconds. A clear understanding of the acceleration and the slope's angle is crucial for solving the problem. The discussion emphasizes the need for step-by-step explanations to clarify the application of these equations.

A body is thrown up on a slope. It reaches a point (l, say) 2 times: at t1 = 1sec and t2=2sec. What is the initial velocity with which it is thrown

Steps and explanation will be helpful
Thank u

Please post your thoughts on the problem and your area of difficulty.
 
What equations have you got to work with?

Where will the body be at 1.5 seconds?
 
I do not know where to start with the problem. I can work with the simple equations of motion

s=ut+(at^2)/2
v=u+at
 

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}...
