Answer:
35 revolutions
Explanation:
t = Time taken
= Final angular velocity
= Initial angular velocity
= Angular acceleration
= Number of rotation
Equation of rotational motion
Number of revolutions in the 10.7 seconds is 17.13806
Number of revolutions in the 11.2 seconds is 17.36035
Total total number of revolutions in the 21.9 second interval is 17.13806+17.36035 = 34.49841 = 35 revolutions
Answer:
m/s
Explanation:
Position/Displacement is measured in meters (m).
Velocity is measured in meters per second (m/s).
Acceleration is measured in meters per second squared (m/s²).
4.0 is gonna be your answer
It changes because radiation always differs in the atmosphere because of the nuclear plants and of pollution around us. Even though it is indoors.
<h2>The acceleration of car is 0.2 ms⁻²</h2>
Explanation:
When the car moves , the distance covered is calculated by the relation
S = u t + a t²
In this question u = 0 , because car was at rest initially
Thus S = a t²
here S is displacement and a is the acceleration of car
Therefore 360 = a ( 60 )²
Because time taken is one minute or 60 seconds
Therefore a =
or a = 0.2 m s⁻²
