A body with a mass of m = 10 kg changes its speed according to the law: v = 20 + 10t (m / s). Find the force F acting on the body.
To calculate the force acting on a taken body, we apply Newton’s second law: F = m * a = m * V (t) ‘.
Variables and functions: m is the mass of the body taken (m = 10 kg); V (t) is the law of speed variation (V (t) = 20 + 10t).
Calculation: F = m * V (t) ‘= 10 * (20 + 10t)’ = 10 * (0 + 10 * 1) = 100 N.
Answer: The taken body was under the influence of a force of 100 N.
