A) zero
B) 40 m
C) 37 m
D) infinite
Correct Answer: A
Solution :
Given, at \[x=\frac{2}{3},\]t = 0 and v = 0 So, the acceleration at t = 0 is \[a=3x-1=3\times \frac{2}{3}-1\]\[=1\text{m}/{{\text{s}}^{2}}\] As velocity and acceleration both are zero at t = 0, so it will always remain at rest, which implies the distance covered by the particle in 4s is zero.You need to login to perform this action.
