Question

Suppose that the magnitude of the head velocity change was 14 m/s. Find time interval for the collision which would produce a possible concussion with an acceleration of 1000 m/s2?

Answer 1

`t=0.014s`

Step-by-step explanation:

Given data

Change in velocity Δv=14 m/s

Acceleration a=1000 m/s²

Required

Time t

Solution

We know that the acceleration is given by the velocity change over time interval.Therefore

a=Δv/t

Substitute the given values to find time t

So

`1000m/s^(2)=(14m/s)/(t)\\ t=(14m/s)/(1000m/s^2)\\ t=0.014s`
