Subject :NSO Class : Class 9
Two identical balls are at rest side by side at the bottom of a hill. Some time after ball A is kicked up the hill, ball B is given a kick up the hill. Ball A is headed downhill when it passes ball B headed up the hill. At the instant when ball A passes ball B, it has the same.
A Position and velocity as ball B
B Position and acceleration as ball B
C Velocity and acceleration as ball B
D Displacement and velocity as ball B
how?
Ans 1:
Class : Class 9
Ans 2: (Master Answer)
Class : Class 1
The correct answer is B.
Position and acceleration of A is same as that of B at the instant when ball A passes ball B.
Ans 3:
Class : Class 9
acceleration due to gravity should be negative for B while positive for A thus not same
Ans 4:
Class : Class 9
the displacement is same
Ans 5:
Class : Class 9
How position and acceleration will be same at that point?
Ans 6:
Class : Class 10
In this condition how the acceleration is same?
