A pole-vaulter approaches the takeoff point at a speed of 9.00 m/s. Assuming that only this speed determines
the height to which he can rise, find the maximum height at which the vaulter can clear the bar. (4.13m)

A flat plate having dimensions 2m ×2m slides down an inclined plane at an angle of 1 rad to the horizontal at a speed of 6m/sec. The inclined plane is lubricated by a thin film of oil having a viscosity of 30 m pa.s. The plate has a uniform thickness of 20mm and a density of 40000km/m3. Determine the thickness of the lubricating oil film.
