Question

After an impact involving a non-functioning satellite, a paint chip leaves the surface of the satellite at a velocity of +96m/s for 10 seconds.Then the object is hit by an asteroid and the force causes a 180 degree turn and the chip moves for 15 seconds at -58m/s. What is the overall change in position for the 25 seconds?

After an impact involving a non-functioning satellite, a paint chip leaves the surface of the satellite at a velocity of +96m/s for 10 seconds. Then the object is hit by an asteroid and the force causes a 180 degree turn and the chip moves for 15 seconds at -58m/s. What is the overall change in position for the 25 seconds?

Solution

The overall change in position for the 25 seconds is

$$s = v _ {1} t _ {1} + v _ {2} t _ {2} = + 9 6 \frac {\mathrm {m}}{\mathrm {s}} \cdot 1 0 \mathrm {s} - 5 8 \frac {\mathrm {m}}{\mathrm {s}} 1 5 \mathrm {s} = 9 0 \mathrm {m}.$$

Answer: 90 m.
