Question

A wheel rotates with a constant acceleration of 2 rad/s^2 . If tge wheel starts from rest , how many revolutions will it make in the first 10 seconds ?

Answer 1

a=(v-u)/t
putting values
2=(v-0)/10
v=20 rotation/second
So it will make 200 rotations in 10 seconds (20×10=200)
If u got it mark me brainliest.

Answer 2

Answer:

16

Explanation:

GIVEN DATA:

acceleration =2rad/sec^2

initial velocity=0

time given=10sec

TO FIND:

revolutions=?

SOLUTION:

S=v*t+1/2at^2

now put values:

s=0*10+1/2*2*(10)^2

s=100m

AS 1REVOLUTION =360degree=2pi radian

so revolution=100/2*180         as pi=180degree

now answer is  15.92

which is approximately =16
