Calculate the launch velocity needed to successfully land the ball into the bucket for each distance, and enter it in the table below. Remember that the launch angle (θ) was 27.5°, the launch height (yi) was 9.59 m, the height of the bucket opening (yf) was 2.5 m, and the range (75 m) is the catapult-bucket distance.

Legend has it that, many centuries ago, Archimedes jumped out of his bathtub and ran across town naked screaming "Eureka!" after he solved an especially difficult problem.
The initial velocity of a 2.28 kg block sliding down a frictionless inclined plane is found to be 1.11 m/s, What is the angle of the plane with respect to the horizontal

Two metal spheres, each weighing 24-kg are placed 0.05 m apart. Compute the magnitude of the gravitational force the two spheres exert on each other.
In the figure, a block of mass m = 12 kg is released from rest on a frictionless incline of angle ? = 26°. Below the block is a spring that can be compressed 2.8 cm by a force of 330 N. The block momentarily stops when it compresses the spring by 6.9..
