Abody weighs 1000 lbf when exposed to a standard earth gravity of g=32.174 ft/s^2. a. what is its mass in kg? b. what is its weight in n if on moon (gmoon = 1.62 m/s^2)? c. how fast will it accelerate if under a force of 400 lbf on moon and on the earth in m/s.

Answer

given,

weight = 1000 lbf

g = 32.174 ft/s²

mass =

m = 31 slug

1 slug = 14.593 kg

m = 31 x 14.593

m = 452.383 Kg

b) weight on moon

  W = m g

   W = 452.383 x 1.62

   W= 732.86 N

c) we know,

   F = m  a

  400 lbf = 31 slugs x a

  a = 12.90 ft/s²

1 ft = 0.304 m

  a = 3.92 m/s²
