A particle is projected along an inclined plane with a velocity given by the formula

v = 4.4t2 + 10.1t -23.2. Determine the acceleration of the particle when t = 1.5 s.

acceleration in m/s2 =

My Answer

V'=8.8t+10.1
V"=8.8
V"(1.5)= 8.8

acceleration in m/s2 = 8.8

Can you please confirm this is correct.
Thanks
