Question

a student measures how far a classmate walks from a starting point every minute for 4 minutes. they write their data in a table, but their data is incomplete. motion data if the person walked at a constant speed, what is the estimated value of the missing data? a. 25 m b. 50 m c 75 m d. 100 m

Explanation:

Step1: Calculate the speed

Speed \(v=\frac{\Delta d}{\Delta t}\). Using the data at \(t = 2.0\) min (\(d=150\) m) and \(t = 0\) min (\(d = 0\) m), \(v=\frac{150 - 0}{2.0-0}=75\) m/min.

Step2: Find the missing distance

For \(t = 1.0\) min, using the formula \(d=v\times t\). Substitute \(v = 75\) m/min and \(t = 1.0\) min, \(d=75\times1.0 = 75\) m.

Answer:

C. 75 m
