A canon shell moving along a straight li...

A canon shell moving along a straight line bursts into two parts. Just after the burst one part moves with momentum `20 N s` making an angle `30^(@)` with the original line of motion. The minimum momentum of the other part of shell just after the burst is

A

`0N-s`

B

`5N-s`

C

`10N-s`

D

Depends on mass of individual particles

Text Solution

Verified by Experts

The correct Answer is:
C
For the minimum value of momentum of other part it must be directed in nefative Y-direction.

Momentum is conserved along both x & y direction for the minimum value of 'P'
`Py_("net")=0rArrP'-20cos60^(@)=0rArrP'=10N-s`

On a frictionless horizontal surface , assumed to be the x-y plane , a small trolley A is moving along a straight line parallel to the y-axis ( see figure) with a constant velocity of (sqrt(3)-1) m//s . At a particular instant , when the line OA makes an angle of 45(@) with the x - axis , a ball is thrown along the surface from the origin O . Its velocity makes an angle phi with the x -axis and it hits the trolley . (a) The motion of the ball is observed from the frame of the trolley . Calculate the angle theta made by the velocity vector of the ball with the x-axis in this frame . (b) Find the speed of the ball with respect to the surface , if phi = (4 theta )//(4) .

Two smooth balls A and B, each of mass m and radius R, have their centre at (0,0,R) and (5R,-R,R) respectively, in a coordinate system as shown. Ball A, moving along positive x-axis, collides with ball B. Just before the collision, speed of ball A is 4m/s and ball B is stationary. The collision between the balls is elastic.
