Complete Question
While john is traveling along a straight in interstate highway, he notices that the mile marker reads 242 km. John travels until he reaches the 147 km marker and then retraces his path to the 161 km marker. What is John's resultant displacement from the 242 km marker? How far has he traveled answer in units of km
Answer:
The resultant displacement
The total distance traveled by john is
Explanation:
From the question we are told that
The first position of john from the finish point is
The second position of john from the finish point is
The third position of john from the finish point is
Generally the displacement from the 242 km marker is mathematically represented as
Here we used instead of because is further than from the finish point
=>
Generally the total distance traveled by John is mathematically evaluated as
=>
=>

Answer:
B. T
Explanation:
This is because the mass of the Bob does no relate to the period as given by the relationship
T = 2π(√L/g) so double mass is still T
