Question

if wheel of diameter 2m makes 60 revolutions per second, then linear speed of a point on the circumference will be?

Answer 1

Answer:

Explanation:

radius =1m

w= 60*2 pie

v=wr

linear speed = 120pie

Answer 2

Answer:

The linear speed of a point on the circumference will be 120 π  rad/sec

Explanation:

Given: The wheel of the diameter 2m makes 60 revolution per second

To find: Linear speed of a point on the circumference

Solution

The wheel of the diameter 2m

Radius  = 1m

Frequency F= 60 revolution per second

Linear speed:

The measurement of a moving object's actual distance travelled is called linear speed. Linear speed is the rate of motion of an object along a straight line. In simple terms, it is the distance travelled along a linear path in the allotted amount of time.

v = ω × r

Where

(angular velocity(ω)  = 2πF

v = ω × r

v = 2π (60) * (1)

v = 120π rad/sec

linear speed = 120 π  rad/sec

Final answer:

The linear speed of a point on the circumference will be 120 π  rad/sec
