A paper in the journal Current Biology tells of some jellyfish-like animals that attack their prey by launching stinging cells in one of the animal kingdom's fastest movements. High-speed photography showed the cells were accelerated from rest for 700 ns at 5.30 ✕ 107 m/s2. Calculate the maximum speed reached by the cells and the distance traveled during the acceleration.

Explanation:

Given that,

Initial speed of cells is 0 as they were at rest

The acceleration of the cell,

Time, t = 700 ns

We need to find the maximum speed reached by the cells and the distance traveled during the acceleration. Let v is the final speed. So,

Let d is the distance traveled. Using equation of motion as follows :

Hence, this is the required solution.

conservation of mass

mass before something happens = mass afterwards
