Question

A force of 128gf acts on a mass of 490g of 10 s .what velocity will it give to the mass​

Answer 1

1 gf accelerates 1 gram at 981 cm/s per second

128 gf accelerates 490 g at 981 x 128 / 490 cm/s per second

So in 10 sec 10 x 981 x 128 / 490 cm/s is gained.

Or you could convert to MKS (SI) to do it.

Answer 2

Answer:

F*deltat=mv

1 gf = .01N

128*.01*10/.490 = 12.8/.490=26.1 m/s
