A particle has such a curvilinear motion that its x-coordinate is defined by x= 5t³ – 105t
where x is in inches and t in seconds. When t = 2 sec., the total acceleration is 75 in/sec?. If the
y-component of acceleration is constant and the particle starts from rest at the origin when t= 0.
Determine (a) the y-component of the acceleration when t=2 sec., (b) the vertical component
of the velocity when t = 4 sec., and (c) the total velocity when t = 4 sec.
