Physics, asked by cenanktpa9s1r, 1 year ago

A body travels 200 CM in first 2 seconds and 220 CM in the next 5 second calculate the velocity at the end of last 7 seconds from start.
This is the question of Stalin Malhotra book of physics.

Any one who answer this question by full process and in correct way I mark his/her answer as a brainlist

there would be two answer

if the acceleration is constant then the formula will be 200+220/5+7

if the acceleration is not constant the the formula will be dx/dt

cenanktpa9s1r: no wrong answer
BirDamanSingh: what is it??

Case 1 --
Distance travelled = 200 cm
Time taken = 2 seconds

Case 2 --
Distance travelled = 220 cm
Time taken = 5 seconds

Total distance = 200 cm + 220 cm
= 420 cm [ As 1 cm = 1 / 100 m ]
= 420 / 100 m
= 4.2 m
Total time taken = 2 seconds + 5 seconds
= 7 seconds

Average velocity = Total displacement / Total time
Average velocity = Total distance with directiom / Total time
Average velocity = 4.2 m / 7s
= 0.6 m
