AI Thread Summary
A 12.0 kg monkey climbs a rope to reach a banana at 6.90 m, with the rope snapping if tension exceeds 132 N. The calculation begins with using the formula F=ma to determine acceleration, resulting in 11 m/s². Using the kinematic equation, the time to reach the banana is calculated to be approximately 1.12 seconds. The original poster initially doubts their solution but later confirms they resolved the issue. The discussion highlights the importance of correctly applying physics equations to solve motion problems.

Homework Statement



A 12.0 kg monkey starts to climb a long rope to reach a banana located at a height of 6.90 m. The rope will snap if the tension exceeds 132 N. Calculate the least amount of time the monkey could take to reach the banana without breaking the rope.

Homework Equations



F=ma
x=xo +vot +1/2 at2

The Attempt at a Solution



I know that F=ma, therefore 132=12a
a=11m/s2

Then,
6.90 = 0 + 1/2 (11)t2
t2 = 1.25
t=1.12s

Something must be wrong, please help

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 hanged 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...
