Gnesinka [82]3 years ago

The time it takes "to complete one cycle" is a perfect definition for <em>period</em>.
So the <em>2 sec</em> that you measured is the swing's period.

Frequency is just   1/period  (the 'reciprocal' of the period).
For this swing, the frequency is   1/(2sec)  =  0.5 per second = <em>0.5 Hz</em>.

( "Hertz" means "per second")

maksim [4K]

Answer:

the statements the correct one is A

Explanation:

Let's analyze this exercise, vehicles have the same mass and speed, so we can use the momentum impulse ratio

          I = ∫ F dt = Δp

the Δp is the same for both cars since they have the same mass and the same speeds, so the momentum is the same in both vehicles

When they indicate that vehicle A was reduced more than vehicle B, this implies that the force acted for a longer time, to have the largest reduction in size, therefore the impact force was less in car A than in car B

Resisting the statements the correct one is A
