• # question_answer A sphere of radius R is in contact with a wedge. The point of contact is R/5 from the ground as shown in the figure. Wedge is moving with velocity 20 m/s, then the velocity of the sphere at this instant will be: A) 20 m/s B) 15 m/s C) 5 m/s D) 10 m/s

 $20\,\,\sin 37=V\,\,cos37$ $V=20\,\,\tan 37$ $V=20\times \frac{3}{4}$ $V=15\,\,m/s$
