the displacement x of a particle is x = 4t2-15t+25 m
(a) find the position , velocity ,acceleration at t = 0sec
(b) when will the velocity of the particle becomes zero ?
(c) can we call the motion of the particle as one with uniform motion?
when t=0
x=25m
by using differeciation nxn-1
velocity=dx/dt= 2*4*t-1 *15
v=dx/dt =8t-15
t=o
v=-15m/s
a=dv/dt
v=8t-15
=8-0
=8m/s2
b..
v=0=8t-15
8t-15=0
8t=15
t=15/8 secs
v will bcom 0 at 15/8 secs
c.. i dont think so it is a uniform motion
hope this helps u
