A) 15 m/s2
B) 20 m/s2
C) 10 m/s2
D) 8 m/s2
Correct Answer: B
Solution :
From equation of motion, we have\[s=ut+\frac{1}{2}a(2n-1)\] where u is initial velocity, t is time, a is acceleration and n is the particular second. Since u = 0, we have \[150=0+\frac{1}{2}a(2\times 8-1)=\frac{15a}{2}\] \[\Rightarrow \] \[a=\frac{300}{15}\,=20\,m/{{s}^{2}}\]You need to login to perform this action.
