A constant force acts on a body weighing 200 g, imparting a speed of 1 m / s to it for 5 seconds. Determine the force acting on the body.
m = 200 g = 0.2 kg.
ΔV = 1 m / s.
t = 5 s.
F -?
According to 2 Newton’s law, the force F, which acts on a body, is equal to the product of the body’s mass m by the acceleration a, which this force gives to the body: F = m * a.
The acceleration of a body is a vector physical quantity, which is determined by the formula: a = ΔV / t and shows how quickly the body’s speed changes over time.
The formula for determining the force will take the form: F = m * ΔV / t.
F = 0.2 kg * 1 m / s / 5 s = 0.04 N.
Answer: force F = 0.04 N. acts on the body.
