Q. A 10.3-kg monkey climbs a uniform ladder with weight w = 1.31 102 N and length L = 2.40 m as shown in the figure below. The ladder rests against the wall and makes an angle of θ = 60.0° with the ground. The upper and lower ends of the ladder rest on frictionless surfaces. The lower end is connected to the wall by a horizontal rope that is frayed and can support a maximum tension of only 80.0 N.
(i) find out the normal force exerted on the bottom of ladder.
(ii) Find the tension in the rope when the monkey is two-thirds of the way up ladder.
(iii) Find out the maximum distance d (along the ladder) that the monkey can climb up the ladder before rope breaks.
Paul is what most people consider a "jock." He is the captain of both the football and wrestling team and he also plays hockey. Upon entering Mrs. Title's class she figured that he would not take course seriously nor would he excel in class. She p..
The springs of a 1300kg car compress 6.00 mm when its 68 kg driver gets into the driver's seat. If the car goes over a bump, what would be the frequency of vibrations.
An object at rest explodes into three pieces of equal masses. One moves east at 23 m/s, while the second piece moves northwest at 14 m/s. Estimate the velocity of the third piece? Suppose each piece has a mass of 2 kg.
A car travelling at 16 m/s runs out of gas while travelling up a 21 degree slope. How far up the hill would it coast before starting to roll back down.
solenoid is formed by winding 23.0 m of insulated silver (resistivity 1.59 x 10-8 Ω·m) wire around a hollow cylinder. The turns are wound as closely as possible without overlapping, and insulating coat on the wire is negligibly thin.
what is the potential difference between the plates.Take the zero of the gravitational potential energy to be at the position of the child as the ropes are horizontal.
Rank the voltage across each cylinder. A baseball is seen to pass upward by a window 15 m above the street with a vertical speed of 18 m/s. imagine the ball was thrown from the street. What was it's initial speed.
An electron is accelerated from rest by the potential difference of 461 V. It then enters a uniform magnetic field of magnitude 184 mT with its velocity perpendicular to the field. Calculate (a) speed of the electron and (b) radius of its path in ..
An ice block is pushed horizontally on a frictionless surface with initial velocity v0. At some point, it comes to the nearly semicircular bump with a radius R=0.42m and the height h=0.33m above the ground.
One mole of nickel (6E23 atoms) has a mass of 54 grams, and its density is 8.9 grams per cubic centimeter. You have a long thin bar of nickel, 2.0 m long, with a square cross section, 0.12 cm on the side.
A violinist places her finger so that the vibrating section of a 1.20 g/m string has a length of 40.0 cm, then she draws her bow across it. A listener nearby in a 20 ^circ {rm C} room hears a note with the wavelength of 30.0 cm. What is the tensio..
