Question

answer plss for 3 questions ​

Answer 1

Answer:

So let's begin

3. as the displacement is zero velocity will be 0

for average speed,

dist. travelled(s) = 10×2

= 20m

time taken(t). = 8 sec

so avg. v = s/t

= 20/8

= 2.5 m/s

4. dist. travelled(s) = 225km

= 225 000 m(standard unit)

time taken(t). = 5 hrs

= 18000 sec

so avg. v = s/t

= 225000/18000

= 12.5 m/s

5. ans is B
