Q. A 10.0-kg monkey climbs a uniform ladder with weight w = 1.31 102 N and length L = 3.0 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.
(a) Find the normal force exerted on the bottom of the ladder.
(b) Find the tension in the rope when the monkey is two-thirds of the way up the ladder.
(c) Find the maximum distance d (along the ladder) that the monkey can climb up the ladder before the rope breaks.
The bowling ball has a diameter of 20.6 {rm cm}, and the angle the stick makes with the horizontal is 30.0 {rm ^circ}. You may suppose there is no friction between the stick and the bowling ball, though friction with the floor must be taken into acco..
A 56.0 kg person jumps from rest off the 9.0 m high tower straight down into the water. Neglect air resistance throughout the descent. She comes to rest 3.40 m under the surface of the water. Find out the magnitude of the average force that the water..
An object that hangs form the ceiling of a staionary elevator by an ideal spring scilliates with a period T. If the elevator accelerates upward 2g , what will the period of oscillation of the object ?
A cart of mass M = 1.2 kg can roll without friction on a level track. A light string draped over a light, frictionless pulley connects the cart to a hanger with mass m = 0.5 kg. The cart is released from rest, allowing it to roll, pulled by falling h..
A 0.39 kg iron horseshoe that is initially at 745°C is dropped into a bucket containing 24 kg of water at 46°C. What is the final equilibrium temperature? Neglect any heat transfer to or from the surroundings.
A driver in a car travelling at the speed of 78 km/h sees a cat km away on the road. How long will it take for the car to accelerate uniformly to a stop in exactly 99 m.
An object whose weight is 100 Ibf experiences a decrease in kinetic energy of 500 ft. Ibf and an increase in potential energy of 1600 ft. Ibf. The initial velocity and elevation of the object, each relative to surface of the earth, are 50 ft/s and 40..
The average intensity of sunlight at the top of the earth's atmosphere is 1390 W/m2. What is the most energy that a 30 m multiplied by 55 m solar panel might collect in one hour in this sunlight.
You're driving down the highway late one night at 18 when a deer steps onto the road 36 in front of you. The reaction time before stepping on the brakes is 0.50, and the maximum deceleration of your car is 12.
A generator uses a coil that has 140 turns and a 0.50-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. assume that each turn of the coil is a square (an approximation), find out the length of the..
