Question

the position of a particle moving in a straight line is given by x=3+4t+3t2, where x is in metre and time is in second.Find the values of the following physical quantities for the particle at t=2s.(i)position.(ii)Displacement (iii)Velocity (iv)Acceleration

Answer 1

position is x=23
displacement is 20m
velocity=16m/s
acceleration=6m/s^2
