Part 1/2
A cyclist maintains a constant velocity of 7 m/s headed away from point A. At the.aome.initial time, the cyclist is 240 m from the point A. What will be his displacement from starting point after 65 s ?
Answer in units m
Part 2/2
Qhat will be his position from point A after that time ?
Answer in units of m
To calculate the cyclist's displacement from the starting point after 65 seconds, we can use the formula:
Displacement = Initial position + Velocity × Time
In this case, the initial position of the cyclist is 240 m away from point A, and the velocity is given as a constant 7 m/s.
So, the displacement will be:
Displacement = 240 m + (7 m/s) × (65 s)
To find the numerical answer, we can plug in these values and solve the equation:
Displacement = 240 m + (7 m/s) × (65 s)
Displacement = 240 m + 455 m
Displacement = 695 m
Therefore, the cyclist's displacement from the starting point after 65 seconds is 695 meters.
Now, to calculate the cyclist's position from point A after 65 seconds, we just need to subtract the displacement from the initial position:
Position from point A = Initial position - Displacement
Using the values given in the previous part:
Position from point A = 240 m - 695 m
Position from point A = -455 m
Therefore, the cyclist's position from point A after 65 seconds is -455 meters. Note that the negative sign indicates that the cyclist is now on the opposite side of point A.
