Question

Hii guys,
can you pls answer these questions step by step.​

Answer 1

Answer:

i) acceleartion! = intial position - final position /time

a =v-u /t

a = 15- 0 /10

a = 15 /10

a =1.5 meter per sec square

ii) decelaration = intial postion -final postion /time

negative acc = v-u/t

negtive acc = 0 - 15 /6

negative acc= -15 / 6

= -5/2

= - 2.5 meter per sec square

iii) distance coverd by body = total speed * total taken time

1/2 * 15 * 10 + 1/2 *15 *6

15 *5 + 15 *3

= 75 +45

=120 meter

follow me dear for.understanding answer
