Question

a particle falls freely under gravityfrom a height h if g is 10 m/S2 and the distance covered in the last second is 10 m then the time after which body hits the ground ​

Answer 1

Answer:

ANSWER

We know that second equation of motion is given by

S=ut+

2

1

gt

2

where S = distance, u = initial velocity = 0 , t = time , g = acc. due to gravity

⇒S=

1

gt

2

Since, u=0
