Question

pls tell me the answer , pls write if only u know the answer pls

Answer 1

Answer:

here is the answer

Explanation:

We know

Velocity = Displacement /Time

(i) d1 at time 35s = 65m

displacement 2 at time 55s = 0 m

Velocity = displacement/t

= d2- d1/t2 - t1 = 0-65 / 55-35

= 65/20 = 3.25 m/s

(ii) Velocity = displacement/t

= 50-50/30-20 = 0m/s
