ROTATIONAL KINEMATICS‚ MOMENT OF INERTIA | 1. A child is pushing a merry-go-round. The angle through the merry-go-round has turned varies with time according to θ(t) = γt + βt3‚ where γ = 0.400 rad/s and β = 0.0120 rad/s3. a. Calculate the angular acceleration as a function of time. b. What is the initial value of the angular velocity? c. Calculate the instantaneous value of the angular velocity at t =5.00 s and the average angular velocity for the time interval t = 0 to t = 5.00 s. 2. At t

M1 SUVAT Equations 1. An aircraft moves along a straight horizontal runway with constant acceleration. It passes a point A on the runway with speed 16 m s–1. It then passes the point B on the runway with speed 34 m s–1. The distance from A to B is 150 m. (a) Find the acceleration of the aircraft. (3) (b) Find the time taken by the aircraft in moving from A to B. (2) (c) Find‚ to 3 significant figures‚ the speed of the aircraft when it passes the point mid-way between A and B. (2) (Total

the time taken for 2000cc mid-size cars from Japan and Germany cars to reach 100km/h. The Japanese cars acceleration was a bit slower than the Germany cars with the same engine capacity. The Honda Accord was clocked at 10.7 seconds when it reached from 0-100km/h. The second car was the Toyota Camry‚ scored a 12.5 second for its trial. The next car was the Nissan Teana that achieved a time of 12.1 seconds. So‚ the overall best car for mid-size 2.0 cars from japan is the Honda Accord. For the Germany

Abstract: In this investigation‚ a mass was attached to a string and was swung horizontally for certain number of rotations (ten). The sole goal for this investigation was to find and verify the relationships between Centripetal Force‚ Frequency and Radius of circular path. In order to get relationships between the variables mentioned above‚ this experiment was divided into two parts. In Experiment A‚ the radius of the path (length of the string)‚ along with the mass was kept constant‚ and the relation

The purpose of this experiment is to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force. Theory All dense objects in free fall have the same acceleration‚ which is known as the acceleration due to gravity. The value of acceleration due to gravity is approximately 9.80 m/s2. In this experiment‚ a vertical stand with an electromagnet at the top for holding and then releasing of the falling body‚ called the plummet. The plummet

Finding the Acceleration of a Ball Problem Statement: How does the height of a ramp that is comprised of two parallel rulers affect the speed of a steel ball bearing rolling down it? Hypothesis: If the steepness of the ramp based on the amount of books propping it up are increased‚ then the steel ball bearings’ speed will increase. Materials: 2 wooden meter sticks 1 steel ball bearing 5 workbooks A roll of masking tape A stopwatch A smooth‚ long surface (preferably a table) Procedures: Arrange
