In the instant shown in the diagram the board is moving up (vertically) with velocity `v`. The drum winds up at a constant rate `omega`. If the radius of the drum is `R` and the board always remains horizontal, find the value of velocity in terms of `R, theta, omega`.

In the block moves up with constant velocity v m/s. Find F

If block A is moving horizontally with velocity v_(A) , then find the velocity of block B at the instant as shown in fig.

If block A is moving horizontally with velocity v_(A) , then find the velocity of block B at the instant as shown in fig.

When a projectile is fired at an angle theta w.r.t horizontal with velocity u, then its vertical component:

(A): If a bomb is dropped from an acroplane moving horizontally with constant velocity then the bomb appears to move along a vertical straight line for the pilot of the plane. (R): If a bomb is dropped from an aeroplane moving horizontally with constant velocity then horizontal component of velocity of the bomb remains constant and same as the velocity of the plane during the motion under gravity

The vector relation between linear velocity vec v ,angular velocity vec omega and radius vector vec r is given by
