8) Un contenitore cilindrico e un contenitore conico hanno la stessa altezza, pari a 10 cm , e la stessa area di base, pari a \( 103 \mathrm{~cm}^{2} \). Entrambi poggiano con la loro base su un piano orizzontale e sono interamente riempiti con un olio avente una densità di \( 900 \mathrm{~g} / \ell \). Assumendo che sia \( g=10 \mathrm{~m} / \mathrm{s}^{2} \), l'intensità della forza esercitata dall'olio sul fondo del recipiente è:

Calculate the following: 1.1.1 The resultant velocity in magnitudo and direction 1.1 .2 The distance the ship will cruise in 5 hours

5) Dos puntos, A y B, están en la misma horizontal separados por una distancia de 500 m . Desde A parte un móvil hacia B, con una rapidez de \( 7 \mathrm{~m} / \mathrm{seg} \), y con una acelerc ción de \( 2,6 \mathrm{~m} / \mathrm{seg} \) ? . Dos segundos después y desde B, parte otro móvil hacia A con una rapidez inicial de \( 16 \mathrm{~m} / \mathrm{seg} \) y una aceleración negativa de \( 1,3 \mathrm{~m} / \mathrm{seg}^{2} \). Calcular donde y cuando se encuentran.

A 63 kg student is on a 15 m diameter Ferris wheel rotating at a constant rate with a period of 18 s . What force does the seat exert on the student at the bottom of the circle?

A car with a mass of 800 kg accelerates uniformly from rest to \( 100 \mathrm{~km} / \mathrm{h} \) for 8 seconds up an incline that makes an angle of \( 30^{\circ} \) with the horizontal. The frictional resistance is 280 N . Calculate: 3.2.1 The work done against the frictional force when the velocity reaches \( 100 \mathrm{~km} / \mathrm{h} \) \( \begin{array}{l}\text { The work done against the gravitational component parallel to } \\ \text { 3.2.2 the plane }\end{array} \)
