Analiza el movimiento del objeto que se representa mediante la gráfica de la Figura 2.21. a. Describe el movimiento del objeto. b. Calcula la aceleración durante los primeros 8 s. c. Calcula ¿cuál es la distancia total recorrida en 12 s? d. Determina ¿cuál es el desplazamiento total al cabo de 2 s? e. Determina ¿cuál es la rapidez media durante el intervalo de 12s?

The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
