Scientists use sonar machines in order to map the contour of the ocean floor. the data from the sonar machines make a model of the ocean floor. what information can be obtained from this model?

What is the final velocity of the initial velocity of 25 and -50?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Abowling ball rolling down the lane toward the pins has gravitational potential energy. a. no b. a lot of c. a little
