A particle initially at rest moves along x axis

Asked by admin @ 20/08/2021 in Science viewed by 331 People

A particle initially at rest moves along the x-axis. Its

acceleration varies with time as a = 4t. If it starts fromthe origin, the distance covered by it in 3s is1)12m2)18 m3)24 m4)36 m.(ans 18m how??-chapter kinematics )

Answered by admin @ 20/08/2021

If we integrate given a=4t then we get velocity and again integrating we gate distance and put time in that , you get 18m.
