A spaceship drifts sideways in outer space from point P to point Q as shown in the figure. The spaceship is subject to no outside forces. Starting at position Q, the spaceship’s engine is turned on and produces a constant thrust (force on the spaceship) at right angles to the line PQ. The constant thrust is maintained until the spaceship reaches another point R in space. As the spaceship moves from Q to R, its speed is

The diagram represents a multiflash photograph of an object moving along a horizontal surface. The positions indicated in the diagram are separated by equal time intervals. The first flash occurred just as the object started to move and the last just as it came to rest. Which of the graphs 1-5 best represents the object’s acceleration as a function of time?
