Answer:
Step-by-step explanation:
Work is said to be done when a force applied to an object cause the body to move in a specified direction.
Work-done = Force * Distance
Since Force = mass * acceleration due to gravity
Work-done = mass * acceleration due to gravity * distance
Given mass = 1.4kg, distance = 0.7m and g = 9.8m/s²
Workdone in lifting the book off the floor = 1.4*0.7*9.8
Workdone = 9.604Joules
- Similarly, work done in lifting a 21-lb weight book 6 ft off the ground is expressed using the same formula as above;
Given mass = 21-lb, g = 32ft/s² and distance = 6ft
Workdone = 21 * 32 * 6
Workdone = 4,032 lb-ft²/s²
Hence, work-done in lifting a 21-lb weight book 6 ft off the ground is 4,032 lb-ft²/s²
Answer:
$516.48
Step-by-step explanation:
Base salary is what Pete will be paid whether he makes a sale or not.
Sales commission is the percentage of the value of the sale that Pete makes which is added to his base salary.
Base salary = $400
Total sales last week = $1456
Commission = 8% of total sales
Commission of last week = 8% of $1456
= 0.08*1456 = $116.48
Gross salary = base salary + commission
= 400 + 116.48
= $516.48
Answer:
The answer is 25
Step-by-step explanation:
(5x)^2=25^2
5x times 5x is 25x^2
25^2 divided by 5x is 5x
The two x's become x^2 and the two 5's just multiply to 25
