The curvilinear motion of a particle is defined by Vx = 25 = 8t and y = 50 -2t2 where Vx is in m/s, y is in metres and t is in seconds. It is also known that x = 0 when t = 0. Determine velocity and acceleration of particle when y = 0.

a package of mass 10kg is released from rest on a rough slope inclined at 25 degrees to the horizontal. after 2 seconds the package has moved 4m down the slope. find the coefficient of friction between the package and the slope.

a box of mass 2kg is pushed up a rough plane by a horizontal force of magnitude 25N. the plane is inclined to the horizontal at an angle of 10 degree. given that the coefficient of friction between the box and the plane is 0.3, find the acceleration of the box.
