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.
A 15.00 block is attached to a very light horizontal spring of force constant 450 and is resting on a smooth horizontal table. Suddenly it is struck by a 3 stone travelling horizontally at 8 to the right, whereupon the stone rebounds at 2.00 horizont..

A 59.0 kg skateboarder wants to just make it to the upper edge of a "quarter pipe," a track that is one-quarter of the circle with a radius of 3.80 m.
In a nebula, the amount of interstellar extinction in the visible wavelength band is 1.1 magnitudes. The thickness of the nebula is estimated to be 16 pc and it is located 458 pc away.
The Apollo Lunar Module was used to create the transition from the spacecraft to the moon's surface and back. Consider the similar module for landing on the surface of Mars. Use conservation of mechanical energy to answer these questions.
A car drives north at 42 mi/h for 10 {rm min} and then turns east and goes 5.0 {rm mi} at 62 mi/h. at last, it goes southwest at 30 mi/h for 6.0 {rm min}.
Find the force to keep object moving.
Find the distance point P on the tip of the blade has traveled in 3 sec. Also, find the magnitude of the acceleration of point P when t = 3 sec.
A 950-kg car traveling west at 15.0 m/s collides with a 750-kg car traveling north at 20.0 m/s. The cars stick together. Find the speed of the wreckage just after the collision
