Answer:
The linear velocity in miles per our is 14789400 mph .
Step-by-step explanation:
Given as :
The radius of wheel = 50 inches
So, the diameter of wheel = 2 × radius = 2×50 = 100 inches
Or, Diameter = 100 × 1.57 miles = 157 miles
The number of revolution per minutes = 500 RPM
or, The number of revolution per hours = 500 × 60 = 30,000 RPH
Now, Circumference of wheel = ×diameter
Or, C = 3.14 × 157 = 492.98 miles
So, Distance cover by wheel = C × RPH × Time in hour
or, D = 492.98 × 30,000 × Time in hour
And Velocity =
or, V =
or, V = 14789400 miles per hour
Hence The linear velocity in miles per our is 14789400 mph . Answer
