Question

A Ball is released from the top of a tower. The ratio of work done by force of gravity in first second and third second of the motion of the ball is

1) 1:2:3
2) 1:4:9
3) 1:3:5
4) 1:5:3

Answer 1

help in physics

Answer 2

we can rule out 4)

Answer 3

i think 3 is the answer but no specific solution of this

Answer 4

it is 3

Answer 5

w = fd
force is constant
only displacement is different

Answer 6

how

Answer 7

ok

Answer 8

so u can calculate displacement in 1st second ,2nd secineand 3rd secon and compare

Answer 9

ok
