Question

A body rotates about a fixed Axis with an angular acceleration of 1 Radian per second square through what angle does it rotate during the time in which its angular velocity increases from 5 Radian per second to 15 Radian per second

Answer 1

So we are given that

alpha(a) = 1 rad/s square

angular initial velocity = 5
final angularvelocity=15

applying

w( f) = w(i) + at
15=5+1t
t=10 sec


now,

we know
theta = w/t
= 15/10
= 1.5 rad

thanksfor asking

Answer 2

Explanation:

the angle rotating by it during the time when it's angular v increases from 10rad to 20rad is 50
