Question

physics question. please answer ASAP​

Answer 1

THESE NUMERICAL DOES NOT NEED ANY MATHEMATICAL CALCULATIONS BUT NEEDS JUST A VERY SIMPLE LOGIC.

In 7th sec., distance travelled 20 m

In 9th sec., distance travelled 24 m

In 11th sec., distance travelled 28 m

In 13th sec., distance travelled 32 m

In 15th sec., distance travelled 36 m

THUS, BY APPLYING THE LOGIC, WE CAN SAY, THE DISTANCE TRAVELLED BY IT IN THE 15th SECOND IS 36 metre.
