Un bloque de hielo con masa de 4.00 kg está ini-
cialmente en reposo sobre una superficie horizontal sin fricción. Un
obrero le aplica entonces una fuerza horizontal F y el bloque se mueve sobre el eje x, de modo que su posición en función del tiempo está dada por x(t) = at + bt , donde a = 0.200 ms , b = 0.0200 ms . a) Calcule la velocidad del objeto en t = 4.00 s. b) Calcule la magnitud
de F en t = 4.00 s. c) Calcule el trabajo efectuado por la fuerza F durante los primeros 4.00 s del movimiento.

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

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
