Answer to Question #230906 in Civil and Environmental Engineering for syra

Question

A body is mass m is moving in a straight line with an initial velocity of 2 m/s from its origin at t=0 and acceleration 6t

Answer 1

We can find the time moved by the moving body,

$Mass = m\\ V_i= 2 m/s\\ V_f=0 m/s\\ a= 6t\\ F= ma\\ m= \frac{F}{a}\\ m= \frac{F}{\frac{2}{t}}\\ But \space a=\frac{2}{t}\\ \implies 6t = \frac{2}{t}\\ \therefore t=0.57735$
