Question

@wasiqss How is it 50 pi radians per second? If you contradict an answer you should provide a reason.

Answer 1

original question?

Answer 2

the speed was 25 m/s,so it means 25 rev in one second, hence 1 rev = 2pie so multiply 2 pie with 25

Answer 3

25 m per second does not mean 25 rev in 1 sec since 1 rev is pi m not 1 meter

Answer 4

I wanna know the question as well now

Answer 5

it would help if we know size of wheel

Answer 7

a truck is moving at a rate of 90km/hr, and the diameter of its wheel is 1 meter. find the angular speed of the wheels in radians per second.

Answer 8

it is a circumference of pi

Answer 9

Of course. That is what I said.

Answer 10

I know, just backing you up

Answer 11

It is 50 rad/sec

Answer 12

diameter was one meter

Answer 13

Yep so 1 revolution is C = Pi times diameter or pi meters

Answer 14

90000
------- = cycle per hours
2 pi .5

90000
------- 1/3600 = cycle per second
2 pi .5

90000
------- *2pi*1/3600 =(90000/.5)*1/3600= radian per second

Answer 15

i rev= 2pie, hence 25 rev means 50 pie

Answer 16

who said 25 rev?
