Question

What is the value of i) distance travelled ii) displacement covered by the object in 30s

Answer 1

Answer:

distance = 237.5 m

displacement = 137.5

Explanation:

For distance just add all the area

i.e.  $s=\frac{1}{2} (10)(10) + \frac{1}{2} (15)(15) + (15)(5)$

∴ s = 237.5 m

For displacement ⇒

$s= -\frac{1}{2}(10)(10) + \frac{1}{2}(15)(15) + (15)(5)$

∴ s = 137.5 m
