Three forces act on a material point with a mass of m = 0.5 kg. The force F2 is 4 N. What is the acceleration value of the point?

acceleration (a) is found by the formula:
a = F / m,
where F is the force acting on the body,
m is body weight.
by condition, three forces act on the body: gravity (mg), support reaction force (N), and traction force (Ftyag). mg and N are equal in modulus to each other, that is, they add up to zero. the traction force remains, its value is known to us – 4 N. it remains to calculate the acceleration:
a = 4 / 0.5 = 8 m / s ^ 2
answer: a = 8 m / s ^ 2
