A single force with x-component Fx acts on a 500 g object as it moves along the x-axis. A graph of Fx versus t is shown in FIGURE . Draw an acceleration graph (ax versus t) for this object.

Problems 44 describe a situation. For each, draw a motion diagram, a force-identification diagram, and a free-body diagram.
A Styrofoam ball has just been shot straight up. Air resistance is not negligible.
A constant force is applied to an object, causing the object to accelerate at 8.0 m/s2. What will the acceleration be if
a. The force is doubled?
b. The object鈥檚 mass is doubled?
c. The force and the object鈥檚 mass are both doubled?
d. The force is doubled and the object鈥檚 mass is halved?
Is the statement 鈥淎n object always moves in the direction of the net force acting on it鈥 true or false? Explain.
The leaf hopper, champion jumper of the insect world, can
jump straight up at 4 m/s2. The jump itself lasts a mere 1 ms before the insect is clear of the ground.
a. Draw a free-body diagram of this mighty leaper while the
jump is taking place.
b. While the jump is taking place, is the force of the ground on
the leaf hopper greater than, less than, or equal to the force of
gravity on the leaf hopper? Explain.
