Question

The velocity time graph of a body moving in a straight line is given. Find the displacement and distance travelled by body in 6 seconds.
Answer fastly Plz..

Answer 1

Displacement =4.5*2-1.5*2+2.5*2=9-3+5=11m
Distance
=4.5*2+1.5*2+2.5*2=9+3+5=17m

Answer 2

Answer: Distance traveled by body is 8 m

According to the graph,

$Velocity\quad =\quad \frac { Distance\quad travelled\quad by\quad the\quad body }{ Time }$

$=\quad \frac { d }{ t }$

$Distance\quad =\quad Velocity\quad \times \quad time$

Distance travelled by the body $=\quad \left( 4\quad \times \quad 2 \right) \quad -\quad \left( 2\quad \times \quad 2 \right) \quad +\quad \left( 2\quad \times \quad 2 \right) \quad =\quad 16\quad m$

Displacement travelled by the body in the 6th second $=\quad \left( 8\quad +\quad 4 \right) \quad -\quad \left( 2\quad \times \quad 2 \right) \quad =\quad 12\quad -\quad 4\quad =\quad 8\quad m$
