A 15.0 kilogram cart initially traveling at 2.0 meters per second east accelerates uniformly at 0.75 meter per second squared ea
Montano1993 [528]

Answer:

Explanation:

Since this is not parabolic motion, it is one-dimensional motion. Very simple. What we are given is

mass: 15.0 kg

initial velocity: 2.0 m/s

acceleration: .75 m/s/s

time: 6.0 seconds

Since we are looking for final velocity, the equation we need for this is

v = v0 + at that says final velocity is equal to the initial velocity plus the acceleration of the object times how long it travels. We don't have a need for the mass here at all.

v=2.0\frac{m}{s}+.75\frac{m}{s^2}(6.0s)

Notice that one of the seconds labels to the right of the plus sign cancel out, leaving us with like units...which we HAVE to have if we want to add.

Simplifying a bit gives us

v = 2.0 m/s + 4.5 m/s so

v = 6.5 m/s

Can the reaction distance be a negitive?
leonid [27]
Yes. Displacement is a vector, as opposed to distance, which is a scalar. Since displacement is a vector quantity, the negative sign represents direction. As with velocity and acceleration, it just comes down to how you define your coordinate system

Simple definition of polar vector​
Assoli18 [71]

Answer:

In physics, a polar vector is a vector such as the radius vector that reverses sign when the coordinate axes are reversed

Explanation:

Polar vectors are the type of vector usually simply known as "vectors." In contrast, pseudovectors (also called axial vectors) do not reverse sign when the coordinate axes are reversed.

A positive charge is placed within the sphere without touching it. You grounded the sphere by touching it with your finger. Then
zhuklara [117]

Answer:

Negative

Explanation:

If a negatively charged object is used to charge a neutral object by induction, then the neutral object will acquire a positive charge. And if a positively charged object is used to charge a neutral object by induction, then the neutral object will acquire a negative charge:

We have a neutral sphere

1) Electrons are attracted to the positive charge

2) Electrons enter the sphere from ground, attrated to the + charge in the sphere

3) The sphere has an excess of e- having entered from the ground

4) Electrons redistribute uniformly
