A 11.0 kg monkey starts to climb a long rope to reach a banana located at a height of 6.50 m. The rope will snap if the tension exceeds 121 N. Calculate the least amount of time the monkey could take to reach the banana without breaking the rope.
Two identical particles, both of mass m and charge q, What is the speed of each particle when they are a distance 2d apart
A 2.00-m tall basketball player is standing on the floor 10.0 m from the basket. If he shoots the ball at a 30 degree angle from the horizontal, at what initial speed must he throw the ball so that it goes through the basket without striking the back..
A golf ball strikes a hard, smooth floor at an angle of 30 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.047 kg, its speed is 45 m/s just before and after striking the floor. What is the magnitude of the impuls..
A sports car moving at constant speed travels 90 m in 4.9s. If it then brakes and comes to a stop in 4s, what is its acceleration? Express the answer in terms of g's, where g = 9.80 m/s2. (Take the positive direction to be direction of travel.)
Suppose you wish to lean a 3.00 m ladder against a smooth, vertical wall. The ladder's center of gravity is 2/3 of length from the top. If the coefficient of static friction between the ladder and the floor is 0.60, what is the largest angle ladde..
Determine the coefficient of kinetic friction between the crate and surface.
A child goes down a playground slide with an acceleration of 1.20 m/s2. Compute the coefficient of kinetic friction between child and slide if the slide is inclined at an angle of 32.2° below the horizontal.
Let the masses of blocks A and B be 4.0 kg and 2.0 kg, in that order, the moment of inertia of the wheel about its axis be 0.400 kg*m^2, and the radius of the wheel be 0.140 m. Find the linear accelerations of block A if there is no slipping between ..
A 43.0-N child is in a swing that is attached to ropes 1.60 m long. Find the gravitational potential energy associated with the child relative to her lowest position at the following times.
A parallel-plate capacitor has a plate area of 1cm^1 and a plate separation of 2.5 mm. To obtain an electric field of 1.0*10^6N/m between the plates, the magnitude of the charge on each plate should be.
Two people stand 5.20 m apart and 4.00 m away from a large plane mirror in a dark room. At what angle of incidence should one of them shine a flashlight on the mirror so that the reflected beam straight strikes the other person.
A parallel-plate capacitor with only air between the plates is charged by connecting it to a battery, A voltmeter reads 46.0V when placed across the capacitor, What is the dielectric constant of this material
