Shown here are the velocity and acceleration vectors for an object in several different types of motion. In which case is the object slowing down and turning to the right
Important Questions on Motion in a Plane
Two parallel discs are connected by a rigid rod of length centrally. Each disc has a slit oppositely placed as shown in the figure. A beam of neutral atoms is incident on one of the discs axially at different velocities , while the system is rotated at angular speed of, , so that atoms only with a specific velocity emerge at the other end. Calculate the two largest speeds (in meter/second) of the atoms that will emerge at the other end.
A clock has a continuously moving second's hand of length. The average acceleration of the tip of the hand (in units of ) is of the order of :
Two particles are moving on two concentric circles of radii and with equal angular speed At their positions and direction of motion are shown in the figure:
The relative velocity at is given by:
