Solution Steps

Step 1: Determine the distance traveled

The curling stone starts at the 0 m mark and stops near the 10 m mark. The question implies the stone stops right at the 10m mark. Therefore, the total distance traveled is 10 m.

Step 2: Find the time taken

The problem requires a time value to determine the velocity. However, the time information is missing from the provided image. Assuming the time taken is 't' seconds.

Step 3: Calculate the velocity

Velocity is defined as distance divided by time. In this case, the distance is 10 m and the time is 't' seconds. Therefore, the velocity (v) is: \(v = \frac{10}{t}\) m/s

Step 4: Find the mass of the curling stone

The mass of the curling stone is not provided in the given image. We'll assume the mass is 'm' kg. A standard curling stone has a mass between 17.24 kg and 19.96 kg.

Step 5: Calculate the kinetic energy

Kinetic energy (KE) is given by the formula: KE = (1/2) * m * v^2. Substituting the velocity calculated in Step 3, we have: \(KE = \frac{1}{2} * m * (\frac{10}{t})^2 = \frac{50m}{t^2}\) J

Final Answer

Velocity: \\( \boxed{v = \frac{10}{t} \text{ m/s}} \\) (where 't' is the time taken in seconds) Kinetic Energy: \\( \boxed{KE = \frac{50m}{t^2} \text{ J}} \\) (where 't' is the time in seconds and 'm' is the mass of the curling stone in kg)

Un projectile est lancé d'une hauteur de 2 mètres avec une vitesse initiale v0 exprimée en m . s^-1. On néglige les frottements de l'air. Le projectile n'est soumis qu'à la force de son poids. La hauteur du projectile, en mètre, est modélisée par la fonction h définie sur [0 ;+infty[ par : h(t)=-1/2 g t^2+v0 t+2, où t est la durée exprimée en secondes et g l'intensité de la pesanteur terrestre. On prendra g=10 m . s^-2. 1. Déterminer la hauteur maximale atteinte par le projectile en fonction de v0. 2. À quel(s) instant(s), au cours de sa trajectoire, le projectile se trouve-t-il à une hauteur de 2 m ? On exprimera les solutions en fonction de v0. 3. On suppose que v0=10 m . s^-1. Calculer l'instant où le projectile touche le sol. On donnera la valeur approchée au dixième. 4. Déterminer la durée pendant laquelle le projectile reste à une hauteur supérieure ou égale à 5 m . On arrondira au dixième.
