The upper estimate for the speed when t=5 using LRAM5
(a)
Answer to Problem 26E
The upper estimate for the speed when t=5 using LRAM5 is
Explanation of Solution
Given information:
Formula used:
The left-hand point rectangle approximation method (LRAM) is used.
Calculation:
For left-hand point rectangle approximation method (LRAM), area is divided into rectangles. Total time is divided into equal intervals and at left-hand point of interval calculates the velocity which is equal to height of rectangle then calculates the area or small rectangles then adds all the area. Total area gives the Speed. There is no need to measure height because we have recorded data.
Use LRAM with 5 equal subintervals. Take the value at left-end point of interval and add all the values then multiply with the length of subinterval which is unity.
Conclusion:
The upper estimate for the speed when t=5 using LRAM5 is
(a)
The lower estimate for the speed when t=5 using RRAM5
(a)
Answer to Problem 26E
The lower estimate for the speed when t=5 using RRAM5 is
Explanation of Solution
Given information:
Formula used:
The right-hand point rectangle approximation method (RRAM) is used.

(c)
The upper estimate for the distance fallen when t=3.
(c)
Answer to Problem 26E
The distance fallen up to 3 second is 146.59 feet
Explanation of Solution
Given information:
Formula used:
The upper estimate formula is used.
Calculation:
Upper estimate for first second
Upper estimate for next second
Upper estimate for third second
So,
Upper estimate for the distance fallen up to 3 second
Conclusion:
The distance fallen up to 3 second is 146.59 feet
