Acceleration Worksheet 3 Worked Example A cheetah running at 20 m s−1 slows down as it approaches a stream. Within 3.0s‚ its speed has reduced to 2 m s−1. Calculate the average acceleration of the cheetah. Solve the following: 1. A sports car‚ accelerating from rest‚ was timed over 400 m and was found to reach a speed of 120 km h−1 in 18.0 s. a. What was the average speed of the car in m s−1? b. Calculate the average acceleration of the car in km h−1 s−1. c. What was

Determination of the Acceleration Due to Gravity By A Good Student Abstract The acceleration due to gravity‚ g‚ was determined by dropping a metal bearing and measuring the free-fall time with a pendulum of known period. The measured value is 9.706 m/s2 with a standard deviation of 0.0317‚ which does not fall within the range of known terrestrial values. Centrifugal forces and altitude variations cannot account for the discrepancy. The calculation is very sensitive to the measured drop

Introduction The Disbursement Acceleration Program of the Aquino Administration should not be implemented because it does not contribute in the GDP and economic growth of the country‚ although it may have been partially successful‚ its rediscovery has drawn reaction as “Unlawful”‚ aside from being unconstitutional‚ it does not serve‚ neither its spending was translated to over-all increase of jobs‚ nor trigger a downturn in poverty incidence. II. Background The Disbursement Acceleration Program (DAP) is a

Calculate the value of t when Q is due north of P. (2) (Total 8 marks) 2. A train starts from rest at a station A and moves along a straight horizontal track. For the first 10 s‚ the train moves with constant acceleration 1.2 m s–2. For the next 24 s it moves with constant acceleration 0.75 m s–2. It then moves with constant speed for T seconds. Finally it slows down with constant deceleration 3 m s–2 until it comes to rest at a station B. (a) (b) (c) Show that‚ 34 s after leaving A‚ the speed

The Home of the Parthenon Marbles The Parthenon Marbles are national treasures of Greece and many years ago‚ were maliciously stolen by Lord Elgin‚ a corrupt business man‚ for his own personal gain. With aid of enemies of Greece and with the full knowledge of the crime Brittan refused to relinquish the stolen property to its rightful owner. The greed and corruption of England has allowed for the long-term confinement of a Greek monument within the dark and winding halls of a dusty British museum

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

The Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge

For over 150 years the marbles of Greece have been placed in the British museum‚ they are recognized as the Elgin Marbles. The Elgin Marbles continue to be the main point of an ongoing debate that will basically determine the historical influence of an important culture. Some of the sculptures that were removed were the marble figures‚ metopes (sculptures in high relief) and friezes. To this day the Greek government has correctly requested the return of the Elgin Marbles a few times while the British
