Question

The average velocity of freely falling body is
7ms! Then it is released from a height equal
to
1.5m 2.10m 3.20m 4. None​

Answer 1

Answer:

The answer is [4. None]

I hope it helps you

Answer 2

Answer:

u of body=0m/s(as it is released from up)

acceleration= - 10m/s²

s=ut+1/2at²(2nd equation of motion)

height=s= -s(as body is moving downward)

now v of body=7m/s

v=u+at

-7=0+( -10*t)

-7= -10t

7/10=t

-s=0*7/10 + 1/2*-10*7/10

-s=-7/2

s=7/2

s=3.5m

therefore answer will be option d
