An object weighing 500kg is to be pulled by
a man by exerting a force P. Force P is
inclined at an angle of 25 deg. measured
from the positive axis. The object and the
floor has a coefficient of friction: static =
0.35 and dynamic = 0.15.
12. What is the total distance travelled by the
object after 5 seconds when the magnitude
of P is equal to 8,000 N? Express your
answer in unit of m
13. What should be the magnitude of P to
cause an acceleration to the object equal to
0.51 m/s^2. Express your answer in unit of
kN.
