Question

A particle moves along the x axis according to the equation x = 2 + 3t - t², where x occurs in m and t in s. At t = 3s, find a) the position of the particle, b) its velocity, and c) its acceleration.

Answer 1

Step-by-step explanation:

i)

at t = 3s

x = 2+ 3×3 - 9 = 2m

ii)

velocity = dx/dt

v = 3 -2t

at t = 3s

v= 3-6 = -3m/s

iii)

acceleration= dv/dt

a = -2m/s^2.
