What is the total mass of the system when a 12 kg box resting on a horizontal frictionless surface is attached to a 5 kg weight?
When a 12 kg box is attached to a 5 kg weight, the total mass of the system is 17 kg.
The maximum speed at which a car can safely negotiate a frictionless banked curve depends on all of the following except?
The maximum speed at which a car can safely negotiate a frictionless banked curve does not depend on the mass of the car. It depends on the angle of the bank, the radius of the curve, and the coefficient of static friction between the tires and the road surface.
A block of mass is held motionless on a frictionless inclined plane by means of a string attached to a vertical wall what is the magnitude of the tension in the string?
The tension in the string would be equal to the component of the gravitational force pulling the block down the incline. This component is given by T = mgsin(theta), where m is the mass of the block, g is the acceleration due to gravity, and theta is the angle of the incline. Since the block is held motionless, this force balances out the component of gravity pulling the block down the incline.
How freight car of mass 20000kg moves along a frictionless level railroad track with a constant speed of 15ms. What is the momentum of the car?
The momentum of the car is calculated by multiplying its mass (20000 kg) by its velocity (15 m/s). Therefore, the momentum of the car is 300,000 kg m/s.
A force of 20 N gives a ball an acceleration of 4.0 ms and Acirc and sup3 on a level frictionless surface What is the mass of the ball?
Using the formula F = ma, where F is the force, m is the mass, and a is the acceleration, we solve for the mass of the ball. Given F = 20 N and a = 4.0 m/s^2, we have 20 = m * 4.0. Therefore, m = 5 kg.
A 9.4kg mass is attached to a light cord that passes over a massless frictionless pulley. The other end of the cord is attached to a 3.2kg mass. Determine final speed after mass 1 falls 4.5m?
A 9.4kg mass is attached to a light cord that passes over a massless frictionless pulley. The other end of the cord is attached to a 3.2kg mass. The final speed after mass 1 falls 4.5m is approximately 6.6 meter per square second.
It is observed that all bodies sliding down a frictionless inclined plane have the same acceleration how does its happen?
Fx=G*sin(t) = m*g*sin(t) a=Fx/m=g*sin(t) ->> does not depend on mass

How to solve obtain the work required to move a 5 kg mass up a frictionless plane inclined at an angle of 30 with the horizontal for a distance of 2 m along the plane in a time of 3.5 s?
Work: don't care about time (that's power) frictionless means don't care about length of plane only care about height and mass -- figure 9.8 m/s*s for acceleration of gravity F=ma F times distance (up) = work good luck
How can you get away in a frictionless surface?
You have to get rid of mass. Throw things, spit, fire a gun if you have one, etc. Since momentum is conserved, every time you get rid of something, you move across the ice in the opposite direction.

What is the velocity of a frictionless falling object 3seconds after being released?
When an object is dropped near the Earth's surface, and it experiences no air resistance, then its speed after 3 seconds is 29.4 meters (96.5 feet) per second, and its velocity is directed toward the Earth's center of mass, nominally the Earth's geometric center, colloquially referred to in the bourgoise vernacular as "down".
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
Describe an experiment for the verification of newton's second law of motion?
Newtons second Law: Force applied on a body is directly proportional to the rate of change of momentum of the body or mass times acceleration (when proper units are chosen, (F = ma). If you change the mass of an object on a (frictionless) surface and apply a constant force the body will acellerate differently. The Mass: a bunch of identiacl items that you can count (metal nuts) in a container with a flat (plastic bottom) Frictionless surface: Flat (wet) glass Force: a spring or rubberband you pull out to a given length befor letting the mass go. Acelleration (stroboscopic photograph, "ticker tape" with constant period marking dots on a paper ribbon... the experiment: Measure the acelleration with mass#1. Repart with twice, three times, four times the mass. Result: Plot the results on log graph paper.
Can mass go down in a chemical reaction?
The mass of reactants is equal to the mass of products.
