PHSCS 121 Final Exam Questions All Solved a driver who is protected by an air bag during a head-on collision is less likely to be seriously injured than an unprotected driver. this is because the airbag - Answer -increases the time interval over which the impulse is experienced 9cm a bullet moving horizontally strikes and sticks in a block of wood that is free to move on the horizontal, level, frictionless surface. the block has a much greater mass than the bullet. what becomes of most ...

KIN 3400 Final Exam : If you jumped from the same height into water as opposed/) If you jumped from the same height into water as opposed to onto concrete, it would take a greater impulse when landing on concrete to reduce your speed to zero velocity assuming you have the same posture at impact in each case a.) True (NOT THIS) (From Rafael’s pictures) b.) False (Correct) 2.) Typically, in which part of a 100m race would expect to find the greatest acceleration? a.) End (NOT This) (From R...

You may accept this project if: A. you are competent in the area of modern control systems B. you do not live in the jurisdiction where the transportation system is being installed C. your original area of specialization was in transportation ...

Kinetic Energy and Jump Height Correct Answer-The relationship between flight height yflight and takeoff velocity vtake-off can be obtained by applying the law of conservation of mechanical energy to the flight phase of the jump. The mechanical energy (E) of the jumper is the sum of the kinetic energy (KE = ½mv2) and gravitational potential energy (PE = mgy). In vertical jumping the effect of air resistance is negligible, and so in the flight phase the jumper can be considered as a projectile i...
