• Newton's second law

  28370 Newton's second law The boy of mass 40kg is sliding down the spiral slide at a constant speed such that his position, measured from the top of the chute, has components r=1.5m, theta=(0.7t)rad, and z=(-0.5t)m, where t is in seconds.

• Soultions to Various Problems in Newtonian Mechanics

  Now the speed of the block when it is sliding over the portion of the incline with friction is given by v(t) = v1 - |a|t where t is the time since the block started sliding down the incline. Thus we have s(t) = v1 t - 1/2|a|t^2.
