Answer:
Explanation:
Acceleration is equal to the change in velocity over the change in time, or
where the change in velocity is final velocity minus initial velocity. Filling in:
Note that I made the backward velocity negative so the forward velocity in our answer will be positive.
Simplifying that gives us:
and then isolating the final velocity, our unknown:
3.0(6.0) = v + 3.0 and
3.0(6.0) - 3.0 = v and
18 - 3.0 = v so
15 m/s = v and because this answer is positive, that means that the car is no longer rolling backwards (which was negative) but is now moving forward.
As per the question, the initial velocity of a object[u] = 0
The acceleration of the object
The time [t] = 12.3 s
We are asked to calculate the velocity of the object at that time.
From equation of kinematics we know that-
V = u+at [Where v is the final velocity of the particle]
=0+4.6*12.3 m/s
=56.58 m/s [ans]
Answer:b the lower leg are inclined planes
Explanation:
Cause I got it right
Transverse waves In transverse waves, particles of the medium vibrate to and from in a direction perpendicular to the direction of energy
Hope this answer helps you
According to KE = (3/2)kT
reducing temperature, in KELVIN, by half, average KE is reduced by half.
