Question

Position time graph of a body of mass 5 kg is
given in the diagram. The impulse on body at
t = 3 s, is
x(m)
18-
12-
6-
1 2 3 4 5
t(s)
(1) 30 kg m s -1
(3) 6î kg m s-1
(2) -30 kg m s -1
(4) -6 kg m s -1​

Answer 1

Answer:

Impulse = final momentum - initial momentum

movementum = m*v

Impulse = 5*0 - 5*6 = -30i
