A convergent lens forms a real image 0.54 times the size oftheobject. The object distance is 38.3 cm. Find the distance ofthefocal point from the center of the lens.

A cannonball is dropped from the top of a building. If the point of release is 38.2 m above the ground, what is the speed of the cannonball just before it strikes the ground?

In the figure, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T₃ = 63.4 N. If m₁ = 15.9 kg, m₂ = 23.6 kg, and m₃ = 38.3 kg, calculate the tension T₂.
