Answer:
Option 3
Step-by-step explanation:
If someone has donated, they must have given at least one item. How can the items be less than the people?!
Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
![a=\dfrac{v-u}{t}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv-u%7D%7Bt%7D)
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
![s=ut+\dfrac{1}{2}at^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cdfrac%7B1%7D%7B2%7Dat%5E2)
Where
s is the distance covered
t is the time
Hence, this is the required solution.
