"q 12.10: a 98 n object is placed 1/3 of the way up a 120 n ladder, which makes an angle of 53 degrees with the horizontal. the lower end is also fastened to the wall by a rope, and both the wall and floor are frictionless. what is the tension in the rope? "

68.829 N

Explanation:

The given parameters are:

Weight of ladder, = 120 N

Weight of object, = 98 N

Angle, = 53°

And we also know that, while

Length of ladder = L

Distance the object is placed = L/3

If we apply translational equilibrium horizontally, then , so

If we apply rotational equilibrium about the distance the object is placed, then

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
