5. (24 points) Two blocks (each of mass 0.725 kg) are initially at rest A + y
with block 2 on the ground and block 1 held directly above it so that '
the string connecting the blocks is taut (not slack). The string’s
length makes the blocks 7.00 meters ap

4. (20 points) A rope of negligible mass is attached to a block of mass m 1 ( 1.50 kg) that
is pulled against a block of mass m 2 (0.740 kg). The blocks remain at rest on a rough
horizontal surface. The rope is under tension, but not enough to move the bl

3. (20 points) A physics student is on another planet and conducts an experiment to
determine g, the acceleration due to this planet's gravity. She throws a ball and sees that
it follows a parabolic trajectory. At t = 1.0 s, the velocity of the ball is
