Answer to Question #167560 in Mechanics | Relativity for Benz

Question

a 12-kg block is acted upon by two forces that are in opposite direction, one a 540 Newton and the other of 1260 N. Determine the acceleration produced. How is the direction of the acceleration related to the forces

Answer 1

According to Newton's second law,

$F_{net}=ma$

$F_1-F_2=ma$

The acceleration of the block is

$a=\frac{F_1-F_2}{m}$

$=\frac{1260 N-540 N}{12 kg}$

=$60 m/s^2$

Direction is towards large force.
