In lieu of energy methods, if you use your relevant equations, Fnet =ma , where Fnet is U(Fn), and Fn is___?, you may find that you can get the acceleratiion without knowing the mass. Then get the distance traveled using the kinematic equations of motion.mmiller9913 said:Homework Statement
An object is given a push along a surface of which the coefficient of kinetic friction is .20. The initial velocity is 4m/s. How far does it go before it stops.
Homework Equations
Fnet=ma
Ff=U(Fn)
The Attempt at a Solution
Is it just me or do you have to know the mass to figure out this problem? I honestly can not seem to get a start on it.
"Finding D from Uk and velocity" is a scientific concept that involves calculating the distance (D) traveled by an object based on its initial velocity (U) and acceleration (a). It is commonly used in physics and engineering to study the motion of objects.
The formula for calculating D from Uk and velocity is D = Ut + 1/2at^2, where U is the initial velocity, a is the acceleration, and t is the time. This formula is derived from the kinematic equations of motion and is commonly used in physics and engineering calculations.
The unit of measurement for D is meters (m), Uk is meters per second (m/s), and velocity can have different units depending on the type of velocity being measured. For example, linear velocity is measured in meters per second (m/s), while angular velocity is measured in radians per second (rad/s).
The concept of "Finding D from Uk and velocity" is relevant in many real-life scenarios. For example, it can be used to calculate the distance a car travels in a certain amount of time, the height of an object thrown in the air, or the distance a projectile travels before hitting a target. It is also important in understanding and predicting the motion of objects in space and in designing structures such as bridges and roller coasters.
While "Finding D from Uk and velocity" is a useful concept, there are some limitations to its application. It assumes that the acceleration is constant, which may not always be the case in real-life situations. It also does not take into account factors such as air resistance, which can affect the distance traveled by an object. Additionally, the formula may not be applicable in situations where the velocity is changing at a non-uniform rate.
