Answer 1

Answer on Question #44910, Physics, Mechanics — Kinematics — Dynamics

THE MOTION OF A PARTICLE IS DESCRIBED BY AN EQUATION X=3t+6t-5t where x is meters and t is seconds find the postion acceleration of particle in 2 seconds.

Solution

$x=3t+6t-5t=4t$

The position in 2 seconds is

$x=4t=4\cdot 2=8\,m$

The acceleration is

$a=\frac{d^{2}x}{dt^{2}}=0$

Acceleration in 2 seconds will be 0 $m/s^{2}$.
