The position of a particu along a
straight line is given by y: 2-5t + t3 (in m)
Find the acceleration of the particle at t 2s.
Is the motion of particu is uniform ?

Explanation:
s = t³-5t+2
t = 2sec
v = ds/dt
= d/dt(t³-5t+2)
= 2t²-5(1)+0
v = 2t²-5 ---(1)
a = d(1)/dt
=d/dt ( 2t²-5)
= 2(2t)-5(0)
a = 4t m/s²
a = 4(2) = 8sec ..:);)
