Question

A force of 20 N acts upon a body whose weight is 9.8 N. What is the mass of the body and how much is its acceleration? Take g = 9.8 m/s2.​

Answer 1

Answer:

Weight = 9.8 N

Weight = 9.8 NW=m×g

Weight = 9.8 NW=m×g9.8=m×9.8

Weight = 9.8 NW=m×g9.8=m×9.8m = 1 kg

Weight = 9.8 NW=m×g9.8=m×9.8m = 1 kgForce, F=mass×acceleration

Weight = 9.8 NW=m×g9.8=m×9.8m = 1 kgForce, F=mass×acceleration20N=1Kg×a

Weight = 9.8 NW=m×g9.8=m×9.8m = 1 kgForce, F=mass×acceleration20N=1Kg×aAcceleration,

Weight = 9.8 NW=m×g9.8=m×9.8m = 1 kgForce, F=mass×acceleration20N=1Kg×aAcceleration,a=20m/s

Weight = 9.8 NW=m×g9.8=m×9.8m = 1 kgForce, F=mass×acceleration20N=1Kg×aAcceleration,a=20m/s 2

Answer 2

Answer:

W=mg

9.8=m*9.8

m=1

f=ma

20=1*m

m=20
