A uniform cube of mass m and edge a moves on a horizontal surface along the positive x-axis, with initial velocity `v_(0)`. Then

A

During motion , Ngtmg

B

During motion, normal reactions acts on the center of mass

C

during motion, the normal reaction shifts towards positive x-axis from the center of mass

D

during motion, normal reaction shifts in the direction of the force of friction.

Text Solution

Verified by Experts

c) According to figure.

In this case, the force of friction has a tendency to rotate the cbe in clockwise directin. So, normal reaction will shift in forward direction to balance the torque due to force of friction.

A uniform solid sphere of mass m and radius r = 3m is projected along a rough horizontal surface with the initial velocity v_(0) = 6m//s and angular omega_(0) velocity as shown in the figure. If the sphere finally comes to complete rest then angular velocity is x rad/s. Find x.

In the adjacent figure, a uniform cube of mass m and edge l=2m is lying at rest an a rough horizontal surface. A small ball of mass m hits the cbe at its top edge with horizontal speed v_(0) and sticks to it. Friction is so large that the cube can rotate about the edge 'O' without sliding. Calculate the minimum value of v_(0) ( in m/s) so that the cube will topple. Ignore any loss of energy due to friction at the edge O and take sqrt(2)-1=0.4 .

A uniform circular disc of radius r is placed on a rough horizontal surface and given a linear velocity v_(0) and angular velocity omega_(0) as shown. The disc comes to rest after moving some distance to the right. It follows that
