Answer:
8.15
Explanation:
From the formula, F = ma we can say:
F = 7.2× a
since a isn't given in the question and f is not also given, we find a.
so a = change in velocity with time
i.e a= V—v ÷ t
therefore, we can say
14.0-8.0 ÷ 5.3
that will give us
6/5.3 =1.132
go back to the formula and put in the parameters
therefore, F = ma gives
F = 7.2×1.132
Ans = 8.15N
