1.Un camión circula por una carretera a 20m/s . En 5 s , su velocidad pasa a ser de 25 m/s ¿ cuál ha sido su aceleración 2.Un fórmula 1 que parte del reposo alcanza una velocidad de 216 km/h en 10 s. Calcula su aceleración

3.Una locomotora necesita 10 s. para alcanzar su velocidad normal que es 25 m/s.
Suponiendo que su movimiento es uniformemente acelerado ¿Qué aceleración se le ha comunicado?

4.Un cuerpo posee una velocidad inicial de 12 m/s y una aceleración de 2 m/s2 ¿Cuánto tiempo tardará en adquirir una velocidad de 144 Km/h?

5.Construir una gráfica de velocidad contra tiempo, para el movimiento de un carro que tiene una aceleración de 4m/s2,durante los primeros 10 segundos de su trayecto. Sabemos que el carro parte del reposo

6.Un automòvil lleva una aceleraciòn de 5 m/s2. Si inicialmente lleva una velocidad de 5 m /s, ¿cuánto tardará el automóvil en alcanzar una velocidad 50 m/s?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
