Question

A wheel with a radius of 45.0 cm rolls without slipping (c) the
along a horizontal floor At time ty, the dot P painted
on the rim of the wheel is at the point of contact between the
wheel and the floor. At a later time tz, the wheel has rolle
through one-half of a revolution. What is the displacement of wheel
during this interval?​

Answer 1

Answer:

168 cm

Step-by-step explanation:

Hope this is helpful for u

Answer 2

the displacement of wheel during this interval is 168cm

Explanation:

Let, d be the displacement

• Horizantal displacement,

                    $x=\pi$×$r$

                      $=45$×$\pi$

                      $=141.37cm$

• Vertical displacement,

                  $y=2r\\ =90cm$

• the displacement of wheel,

       $d=\sqrt{x^{2}+y^{2} }$

           $=168cm$
