AI Thread Summary
The minimum horizontal velocity required for a diver to safely clear the rocks from a 61m high cliff is calculated to be 6.52 m/s. This is determined by the equation 23 = Vx(t), where t is the time taken to fall, which is found to be 3.52 seconds. The vertical motion is analyzed with an initial vertical velocity of 0 m/s and an acceleration of -9.8 m/s², leading to a fall time of 3.52 seconds. The calculations confirm that both the horizontal and vertical components are correctly derived. Therefore, the diver must achieve a horizontal speed of at least 6.52 m/s to ensure safety during the dive.

Please just check my answer.

Divers at Acapulco dive from a cliff that is 61m high. If the rocks below the cliff extend outward for 23m, what is the minimum horizontal velocity a diver must have to clear the rocks safely?

x problem

x=Vx(t)
23=Vx(t)
23=Vx(3.52)
23/3.52=Vx
Answer is Vx=6.52m/s

Y problem

Vy=0m/s
t=?
d=-61m
a=-9.8m/s/s

d=1/2a(txt)+Vi(t)

-61=-4.9(txt)
-61/-4.9=txt
12.44=txt
square root 12.44=txt Answer for Time is 3.52 Seconds

All correct.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
