At time t, the distance x cm of a particle moving in a horizontal line is given by x = 4t sq. + 2t. Find velocity and acceleration when t = 0.5 s.

Here,
X = 4 + 2t
And therefore,
Velocity a time t = v = = 8t + 2.
Acceleration at time t = a = = 8
When t = 0.5 ,
Velocity = 8t + 2
= 8(0.5) +2
= 6 cm/s
And ,
Acceleration= (8) = 8 cm/

v=dx/dt
v=d(4t2+2t)/dt
v=8t+2
v=6
a=dv/dt
a=d(8t+2)/dt
a=8
