O que você entende por posição, velocidade e aceleração em um contexto de funções integradas?

10. The distance travelled by a free falling object varies directly to the square of the time taken. Given that an object dropped a distance of 19.6 m after 2 seconds, find the distance dropped after 5 seconds.

7. Let vectors \( \vec{A}=2 i-3 j \) and an unknown vector \( \vec{B} \) lie on the xy plane, where \( \vec{A} \cdot \vec{B}=4 \) and \( |\vec{A} \times \vec{B}|=4 \) a) Find the angle \( \theta \) between the two vectors b) Find \( \vec{B} \) and express it in terms of rectangular unit vectors

(c) Vektor kedudukan sebuah dron \( A, t \) saat selepas meninggalkan tempat berlepas ialah \( t\binom{30}{15} \) manakala vektor kedudukan dron \( B \) ialah \( \binom{50}{5}+t\binom{10}{10} \). Tentukan halaju bagi dron \( A \) dan dron \( B \). Adakah dron \( A \) dan dron \( B \) akan bertembung? The position vector of a drone \( A, t \) seconds after leaving the takeoff point is \( t\binom{30}{15} \) while the position vector of drone \( B \) is \( \left(\frac{50}{5}\right)+t\binom{10}{10} \). Determine the velocity of drone \( A \) and drone \( B \). Will drone \( A \) and drone \( B \) collide?

must be the charge of a Figure \( 23-40 \) shows a section of a \( R=3.00 \mathrm{~cm} \), with a charge per unit length of \( \lambda=2.00 \times 10^{-8} \mathrm{C} / \mathrm{m} \). What is the magnitude \( E \) of the electric field at radial distance (a) \( r=R / 2.00 \) and (b) \( r=2.00 R \) ? (c) Graph \( E \) versus \( r \) forthe range \( r=0 \) to 2.00R.

3.33 • Uma canoa tem velocidade de \( 0,40 \mathrm{~m} / \mathrm{s} \) a sudeste em relação à Terra. A canoa se desloca em um rio que escoa a \( 0,50 \mathrm{~m} / \mathrm{s} \) para leste em relação à Terra. Determine o módulo, a direção e o sentido da velocidade da canoa em relação ao rio.
