Question 2
A particle moves in a straight line. At time t s, t >0, its
displacement from a fixed origin 0 is x m and its acceleration, a , is given by
a =
If the particle starts at the point x = 3, with a velocity of 2 m/s towars 0,
express x in terms of t.
For the next question, take the acceleration due to gravity to have magnitude g , where g = 9.8
Question 3
A box of mass 3 kg lies on a level floor. The coefficient of friction between the
floor and the box is 0.41. A child pulls on the box with a horizontal force of 10 N.
Show that the box does not move.
