### inertial reference frames?

If only a single nonzero force acts on an object, does the object accelerate relative to all inertial reference frames?

Is it possible for such an object to have zero velocity in some inertial reference frame and not in another? If so, give a specific example.

A straight line is drawn on the surface of a 16-cm-radius turntable from the center to the perimeter. A bug crawls along this line from the center outward as the turntable spins counterclockwise at a constant 45 rpm. Its walking speed relative to the turntable is a steady 2.9 cm/s. Let its initial heading be in the positive x-direction, where the x- and y-directions are fixed relative to the laboratory. As the bug reaches the edge of the turntable (still traveling at 2.9 cm/s radially, relative to the turntable) what are the x and y components of the velocity of the bug?

In basketball, hang is an illusion in which a player seems to weaken the gravitational acceleration while in midair. The illusion depends much on a skilled player's ability to rapidly shift the ball between hands during the flight, but might also be supported by the longer horizontal distance the player travels in the upper part of the jump than in the lower part. If a player jumps with an initial speed of v0 = 6.60 m/s at an angle of θ0 = 40.5°, what percent of the jump's range does the player spend in the upper half of the jump (between maximum height and half maximum height)?

The answer is 1/sqrt2, but I'm not sure how?
