Question

A body starts moving in a straight line under the
influence of a variable force F. Calculate the time
after which the initial velocity of body becomes
equal to the final velocity of body for the given
F-t graph
Fin N)
t(sec)
(1) (2+ 2✓2 )sec
(2) (2+✓2) sec

(3) 4 sec
(4) 2+1/✓2
sec
​

Answer 1

Answer:

1/2*2*2=1/2*2x*x

y we have taken 2x and x means the elongation of line on x axis it is x and on y axis 2x

if we calculate x=root 2

final velocity=2+x

=2+root 2
