9)
- k√y where k is a constant.
The acceleration of a particle is defined by the relation a = -
Knowing that at x =0 and v= 25 ft/s at t= 0 and that v = 12 ft/s at x= 6 ft, determine the
velocity of the particle when x = 8 ft and the time required for the particle to come to rest.
ANS.
v(x) = (125 – 13.91x)²/3 ft/sec
v(x = 8 ft) = 5.74 ft/sec
time to come to rest = 1.08 sec
