billy drops a ball from a height of 1 m. the ball bounces back to a height of 0.8 m, then bounces again to a height of 0.5 m, and bounces once more to a height of 0.2 m. up is the positive direction. what is the total displacement of the ball?\nif you answer is not an integer, round it to the nearest tenths place (1st decimal place).\n______ m
Answer
Explanation:
Step1: Define initial position
Initial height: $y_0 = 1\ \text{m}$
Step2: Define final position
Final height after last bounce: $y_f = 0.2\ \text{m}$
Step3: Calculate displacement
Displacement = final position - initial position $\Delta y = y_f - y_0$ $\Delta y = 0.2 - 1 = -0.8\ \text{m}$
Answer:
$-0.8$ m
