Graham finds a young man‚ an asylum seeker‚ lying stabbed‚ bleeding in the street‚ crying for help. Graham doesn’t want to help as he might get stopped and questioned by the police‚ who might see him as a suspect for the possible assault on this man. Graham has to make the right choice‚ it’s all down to him if he wants to save that young wounded man’s life or face the wrath of

explained by Newton’s three laws of motion. They explain something different of the motion of an object‚ put together they explain everything. In order they are; Newton’s First Law: The law of inertia; Newton’s Second Law: The law with the concept of acceleration; Newton’s Third Law: The Law of Action & Reaction. Newton’s 1st law states that any object at rest will remain at rest or if its moving it will remain moving at a constant speed until force is has acted upon it or is exerted on it. For

Calculate the velocity of the object after 3 seconds and before it hits the ground. What can be the height it is thrown? 6. Calculate the velocity of the car which has initial velocity 24m/s and acceleration 3m/s² after 15 second. 7. The car which is initially at rest has an acceleration 7m/s² and travels 20 seconds. Find the distance it covers during this period. 8. An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the

this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible to use any two points to figure out and calculate acceleration due to gravity. Sir Isaac Newton

is studied. The NS component of the El – Centro earthquake and harmonic ground acceleration is considered for earthquake excitation. The structure is modeled considering six-degrees of freedom (three translations and three rotations) at each node. The sliding support is modeled as a fictitious spring with two horizontal degrees of freedom. The response quantities considered for the study are the top floor acceleration‚ base shear‚ bending moment and base displacement. It is concluded from the study

Law applied to the smaller mass‚ M1‚ implies (see Figure 2b): FNET(on M1) = M1a T– M1g = M1a (2) The tension T can be eliminated from equations (1) and (2) obtain: M2g – M1g = M2a + M1a (3) The magnitude of the acceleration‚ a‚ of the system is then: (4) The numerator‚ (M2 – M1)g‚ is the net force causing the system to accelerate. The denominator‚ (M2 + M1)‚ is the total mass being accelerated. Equation (4) can be written: (5) Where FNET
