Answer:
s(t) = (t1 - t2)* [((1/t1 - 3) + (1/t0 - 3))/2]
Explanation:
We will assume that v(t) is in units of m/s and t (time) is in seconds.
v(t)=1/t−3
At time 0 (initial) the equation tells us the particle has a velocity of
v(t)=1/t−3
v(0)=1/(0)−3
v(0) = - 3 m/s
The particle is moving from right to left (the negative sign) at a rate of 3 m/s.
The position of the particle would be the average velocity times the time traveled.
Distance = Velocity x Time (with Velocity being the average between times t0 and t1)
We'll use s(t) for displacement for time t.
s(t) = v*t
We need the average velocity for the time period t0 to t1.
Let t0 and t1 be the initial and final times in which the measurement takes place.
At time t0 the velocity is = 1/t0 - 3
At time t1 the velocity is = 1/t1 - 3
The displacement is the average velocity between the two points, t0 and t1. This can be written as:
[(1/t1 - 3) + (1/t0 - 3)/\]/2
Displacement: s(t) = (t1 - t2)* [((1/t1 - 3) + (1/t0 - 3))/2]
Answer:
No chemical bonds are broken or formed in melting butter, so it is not a chemical change. The melting process is only a physical change, the change of state from solid to liquid.
Answer:
I think it's physical change because originally it was a solid but now it's a liquid and its chemical properties have not changed only shape
It is greatest at 25% of the period length.
B.
It is greatest at the point where the arm meets the pivot point.
C.

D.
It is greatest when the bob is in the rest position.

ANSWER:
The moving car transfers kinetic energy to the parked car.
EXPLANATION:
Kinetic energy is the energy an object has because of its motion and can be transferred between objects and transformed into other kinds of energy.
When a moving car hits a parked car, causing the parked car to move, the type of collision is elastic collision. An elastic collision is when two bodies collide and separates after collision conserving the total kinetic energy before and after collision.
