A stone weighing 400 g was thrown horizontally with a force of 10 N. With what acceleration did you throw the stone?

According to Newton’s second law:
F = m * a, where F is the force with which the stone was thrown horizontally (F = 10 N), m is the mass of the stone (m = 400 g = 0.4 kg), and is the acceleration of the stone (m / s²).
Let’s express and calculate the acceleration of the stone:
a = F / m = 10 / 0.4 = 25 m / s².
Answer: Acceleration of a stone is 25 m / s².
