A rightward force of 24. 0 n is applied to a 2. 0-kg object to accelerate it across a horizontal surface. The object encounters 16. 0 n of friction. What is the object's acceleration?.

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Física: un futbolista patea hacia el arco con una velocidad de 15m/ah, calcular: a)el alcance para un ángulo de tiro de 25º, b) el tiempo que el balón permanece en el aire.
