(1) A hydraulic press has an input piston with a diameter of 0.375 cm and an output piston with a diameter of 8.0 cm. Calculate the force needed at the input piston to create an output force of 60,000 N.

(2) A 120 kg barrel which is initially at rest is rolled down an inclined plane. The friction between the barrel and the surface of the plane is negligible. If the point where the barrel is released is 1.5 m above the ground at the end of the inclined plane, calculate the barrel's velocity when it reaches the ground level.
