Let us assume SI units are to be used

position x = ( 4t2 -15t + 25 ) m

velocity dx/dt = ( 8t - 15 ) m/s

acceleration = 8 m/s2

Since acceleration is constant, this motion is uniformly accelerated motion.

velocity will become zero when t = 15/8 seconds

at t = 15/8 s, when velocity becomes zero, position of particle = 4×(15/8)2 -15(15/8) +25 ≈ 11 m
