# what is the duration of the impact in seconds assuming the acceleration of the hammer was constant

Chapter 10 Quiz Flashcards | Quizlet- what is the duration of the impact in seconds assuming the acceleration of the hammer was constant ,A 0.2 kg block is held in place by a force F that results in a 0.10 m compression of a spring beneath the block. The spring constant is 1.0 × 102 N/m. Assuming the mass of the spring is negligible compared to that of the block, to what maximum height wouldMomentum Change and Impulse - Physics ClassroomA force acting upon an object for some duration of time results in an impulse. The quantity impulse is calculated by multiplying force and time. Impulses cause objects to change their momentum. And finally, the impulse an object experiences is equal to the

### Velocity to knock over a barrier | Physics Forums

7/4/2015· We know from typical crash testing of vehicle to barrier impacts, that the duration of the impulse is 0.05 to 0.1 seconds (airbag control module data). F = m a = m v / t = impulse v = F t / m, that does not make sense either and would result in a very small number as I do not have the impulse force, but the constant force.

12/4/2010· The mass of the hammer is known (50 lb, or 22.68 kg), and the impact duration is assumed to be 0.1 seconds. The velocity is found using a simple motion equation: where v y is the velocity at impact, v yi is the starting velocity (zero, since it's falling from a standstill), y and y i are the impact and starting heights, respectively, and a is the acceleration of gravity.
