QUESTION: 1

A ball is projected making and angle θ with the vertical. Consider a small part of the trajectory near the highest position and take it approximately to be a circular arc. What is the radius of this circle? This radius is called the radius of curvature (** ROC**) of the curve at the point if

Solution:

The correct answer is: 20

*Answer can only contain numeric values

QUESTION: 2

A small wedge whose base is horizontal is fixed to a vertical rod as shown in the figure The slopping side of the wedge is frictionless and the wedge is spun with a constant angular speed ω about vertical axis as shown in the figure. Find

The value of angular speed ω (*rad/sec*) for which the block of mass ** m** just does not slide down the wedge?

Solution:

The free body diagram of the block is

For block not to slide along wedge, applying Newton's second law along incline we get

The correct answer is: 10

QUESTION: 3

The member ** OA** rotates about a horizontal axis through

Solution:

As the mass is at the verge of slipping

6 – 8µ = 4.5

The correct answer is: 0.1875

*Answer can only contain numeric values

QUESTION: 4

A rod ** AB** is moving on a fixed circle of radius

The speed of point of intersection ** P** is then

Solution:

As a rod ** AB** moves, the point ‘

x = 5

The correct answer is: 5

QUESTION: 5

A squirrel climbing up a cylindrical post spirally makes the circle in a vertical height of four feet. If the top of the post is sixteen feet high and three feet in circumference, the distance travelled by it to reach the top is ** x** in feet. Find the value of x/10

Solution:

Distance traveled in climbing 4 feet is

So, distance traveled in climbing 16 feet will be 20 feet ** x** = 20 feet

x/10 = 2

The correct answer is: 2

*Answer can only contain numeric values

QUESTION: 6

The figure shows the velocity and acceleration of a point like body at the initial moment of its motion. The acceleration vector of the body remains constant. The minimum radius of curvature of trajectory of the body is (in ** m**.)

Solution:

The acceleration vector shall change the component of velocity *u*_{||} along the acceleration vector.

Radius of curvature *r_{min}* means

The correct answer is: 8

QUESTION: 7

A ring of mass 2π kg and of radius 0.25* m* is making 300 -

Solution:

The correct answer is: 250

*Answer can only contain numeric values

QUESTION: 8

A toy car of mass ** m** can travel at a fixed speed. It moves in a circle on a fixed horizontal table. A string is connected to car and attached to a block of mass

Solution:

As the car travels at a fixed speed 1 ** m**/

**Case I :** If hence friction force on car of mass * m* will be outwards from the centre.

hence friction force on the car of mass ** m** will be towards centre.

From equations (1) and (2)

The correct answer is: 6

*Answer can only contain numeric values

QUESTION: 9

A small bead of mass * m* = 1

Solution:

The maximum angular speed of the hoop corresponds to the situation when the bead is just about to slide upwards.

The free body diagram of the beads is

For the bead not to slide upwards

From 1 and 2 we get,

The correct answer is: 30

*Answer can only contain numeric values

QUESTION: 10

A circular curve of a highway is designed for traffic moving at 72 * km*/

Solution:

The correct answer is: 0.4
