The Sears Tower in Chicago is 443 m tall. Joe wants to set the world’sstair climbing record and runs all the way to the roof of the tower. If Joe’saverage upward speed is 0.60 m/s, how long will it take Joe to climb fromstreet level to the roof of the Sears Tower?

Aclarinetist, setting out for a performance, grabs his 3.350 kg clarinet case (including the clarinet) from the top of the piano and carries it through the air with an upward force of 24.65 n. find the case's vertical acceleration. indicate an upward acceleration as positive and a downward one as negative.

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

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.
