Question

question 1 (1 point)
calculate the displacement of this object on the graph below.
position x (m)
time t(s)
a 30 m
b 45 m
c 10 m
d 20 m

Explanation:

Step1: Recall displacement formula

Displacement = final position - initial position.

Step2: Identify initial and final positions

Initial position at \(t = 0\) is \(x_i=0\) m. Final position at \(t = 30\) s is \(x_f = 20\) m.

Step3: Calculate displacement

Displacement \(d=x_f - x_i=20 - 0=20\) m.

Answer:

D. 20 m
