studiot Posted September 17, 2016 Share Posted September 17, 2016 I recommend a standard method for all these problems. Write down a list of all the quantities involved, whether you know them or even need them or not. There are only 5 Initial velocity u = Final velocity v = Distance s = Time t = Acceleration f = Write the numbers you know (are given) against these you know Then write down all the kinematic equations.there are again 5 v = u + ft s = ut + 0.5ft2 v2 = u2 + 2fs f = (v-u)/t s = 0.5(v+u)t Note that only four of the basic quantities appear in each equation. Find the equation in which you know 3 of these four and calculate the fourth. Fill in the numbers in you table of quantities until you have answered your question.
