Question

1 6 Calculate the displacement and distance travelled by the body in 5 s, from the adjoining velocity- time graph.​

Answer 1

→Answer :

Distance = area under graph = area of five parts under graph

$\frac{1}{2} \times 2 \times 20 + 2 \times 20 + 1 \times 20 + \frac{1}{2 } \times 1 \times 20 + \frac{1}{2 } \times 1 \times 40$

• Distance =

$20 + 40 + 20 + 10 + 20 = 110m$

Displacement = area above x axis −area under x axis

= 90−20=70m

→ 110,70.

is the Answer
