A net force of 150 lbs acts on a body whose weight is 96 lbs. What is its acceleration? Please indicate the formula used.

The equation to use is
F = m * a, however, the mass must be in slugs, not pounds, if you are going to use British units. The force an be in pounds, and the value of a will be in ft/s^2.
1 slug is the mass that is accelerated at a rate of ft/s^2 by a force of 1 pound. It equals 32.2 pounds
An object with a weight of 96 lb (on earth) has a mass of
M = 96/32.3 = 2.981 slugs
a = F/m = 150/2.981 = 50.3 ft/s^2. 
Thank you sir! :)
