When person moves in the coordinate system from
A (0, 0) to B (5, 10), to C (8, 6), what is the displacement covered?
a) 10 units
b) 5 units
c) 7 units
d) 15 units

Text Solution

Verified by Experts

The correct Answer is:
B
Let the velocity of the body at AL is for minimum velocity given ta velocity of the body at point B is zero.


Applying law of conservation of energy at A and B
`1/2 mv^2=mgh`
`1/2mv^2=mg(2L)`
`rarr v=sqrt((4gL))=2sqrt(gL)`
