22)))At t = 0, a particle moving with constant acceleration in the xy plane has a velocity v = (3.00i-2.00j) m / s at its origin. At t = 3.00 s, the velocity of the particle is v = (9.00i + 7.00j) m / s. Find the acceleration of the particle?
II. The position coordinate of a
particle which is confined to
move along a straight line is
given by s = 2t3 – 24t + 6,
where s is measured in meters
from a convenient origin and t
is in seconds. Determine (a)
the time required for the
particle to reach a velocity of
72 m/s from its initial condition
at t = 0, (b) the acceleration of
the particle when v = 30 m/s,
and © the net displacement of
the particle during the interval
t = 1s and t = 4s. (Practice at
