In a very busy off-campus eatery one chef sends a 249-g broccoli-tomato-pickle-onion-mushroom pizza sliding down the counter from left to right at 1.67 m/s. Almost simultaneously, the other chef launches a 341-g veggieburger-on-a-bun (with everything, but hold the horseradish) along the same counter from right to left at 2.31 m/s. The two delicacies collide head on at the given speeds-the counter is practically friction-free due to accumulated grease-and merge into a single, unbelievably savory serving. In what direction does the delectible dish move, if it moves at all? At what speed does it move, in a positive number.
A horizontal force of 5.0 N accelerates a 4.0 kg mass, from rest, at a rate of .50 m/s squared in the positive direction. What friction force acts on the mass
what is the compressional stress that the arm withstands during the crash?
And if the plane could fly without this pilot, how much force would the plane require to maintain the equal acceleration?
Monochromatic light of a given wavelength is incident on a metal surface. However, no photoelectrons are emitted. how should the incident light be adjusted
At t=0, the displacement x(0) of a block attached to a spring is -850 cm. The block's velocity v(0) is then -.920m/s, what is the abgular frequency of this system
A particle contains the quark combination: u b, What is the charge of the particle and What is the baryon number of the particle
A uniform meter stick with a mass of 205 g is supported horizontally by two vertical strings, one at the 0 cm mark and the other at the 90 cm mark. what is tension on the string at the 0 cm mark and at the 90 cm mark.
assume that you are a Haitian taptap driverand want a more comfortable ride. You decide to replace the springswith new springs that can handle the typical heavy load on yourvehicle. What spring constant do you want your new spring system to have.
Chameleons catch insects with their tongues, that they can rapidly extend to great lengths. In a typical strike, the chameleon's tongue accelerates at a remarkable 250 m/s^2 for 20 {rm ms}, then travels at constant speed for another 30 {rm ms}.
Two boxes sit side-by-side on a smooth horizontal surface. The lighter box has a mass of 5.96 kg, the heavier box has a mass of 7.46 kg. Calculate the contact force between these boxes
After a golf ball is hit it takes off with an initial speed of 26.2 m/s and at an angle of 39.5° with respect to the horizontal. The golf field is flat and horizontal.
