Question

drag and drop the correct option(s) to complete the sentence(s). the motion of a runner who covers 55 m in 15 s is represented by the this motion diagram. accordingly, the runners total displacement is. the time interval between two successive positions is equal to 18.3 m 15 m 20 s 5 s 55 m 15 s

Explanation:

Step1: Determine total displacement

Displacement is the straight - line distance from the initial to the final position. The runner starts at \(x = 0\) and ends at \(x=55\) m. So, displacement \(d = 55\) m.

Step2: Calculate time interval between successive positions

The runner covers \(55\) m in \(15\) s. There are \(3\) intervals between \(4\) positions. Let the time interval be \(t\). Using the formula \(n\times t=T\) (where \(n = 3\), \(T = 15\) s). Then \(t=\frac{T}{n}=\frac{15}{3}=5\) s.

Answer:

The runner's total displacement is \(55\) m. The time interval between two successive positions is \(5\) s.
