175 A body has a mass of 3217 lb and is accelerated at the r

1.75 A body has a mass of 321.7 lb. and is accelerated at the rate of 5 ft./s^2. Determine the magnitude of the unbalanced force acting on it.

please show work

Solution

mass= 321.7 lb

acceleration (a) = 5 ft/s2

we know according to the newtons second law force F = mass * acceleration

so F = 321.7 * 5 lb ft/s2

= 1608.5 lb ft/s2 is the unbalance force in the body which is generated due to the acceleration of the body
