In Example 5.8, we investigated the apparent weight of a fish in an elevator. Now consider a 72.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.20 m/s in 0.800 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.50 s and comes to rest. What does the spring scale register (a) before the elevator starts to move, (b) during the first 0.800 s, (c) while the elevator is traveling at constant speed, and (d) during the time interval it is slowing down?

A mad scientist invents an antigravity device that shields the region of space above a large metal plate from the earth’s gravitational field. Specifically, if the device is turned on at time t = 0, the effective magnitude of the gravitational acceleration in the region above the plate decreases exponentially with time according to mag(a→a→) = ge−q t , where g is the usual gravitational field strength and q is a constant. When enough time has passed that qt becomes large, the effective gravitational field above the plate becomes very small compared to g. Assume that the value of q is 3.0 when expressed in the appropriate SI units. (a) What are the SI units of q? Choose one _____(m, m/s, s, 1/s) (b) The mad scientist keeps a 10-kg bowling ball on a shelf above the plate. When the mad scientist throws the gigantic wall switch to turn on the apparatus one day, the vibrations jostle the bowling ball loose, and it rolls off the shelf. The scientist watches in horror as the ball smashes into…
Consider a block being pulled from rest through a distance 46.03 cm to the right across a tabletop. A cord that provides a tension with magnitude 19.31 N is attached to the right side of the block and extends horizontally, parallel to the table. As the block slides, the force of kinetic friction between the 1.831 kg block and the table is 2.844 N. Calculate the speed of the block at the end of the 46.03 cm movement. Report to four significant figures, in standard units, but do not include the unit in the answer field.
