Answer:

Revisar las respuestas a cada problema, como se muestra mas adelante.

Explanation:

Para poder solucionar esta serie de problemas debemos de utilizar la segunda ley de Newton, la cual nos dice que la sumatoria de fuerzas sobre un cuerpo debe de ser igual producto de la masa por la aceleracion.

De esta manera tenemos:

ΣF = m*a

donde:

F = fuerza [N]

m = masa [kg]

a = aceleracion [m/s^2]

1 )

F = m*a

60 = m*4

m = 15[kg]

2)

F = m*a

a = 250/50

a = 5 [m/s^2]

3)

F = m*a

F = 80*2.5

F = 200 [N]

4)

F = m*a

800 = 1500*a

a = 0.533[m/s^2]

5)

F = m*a

100 = 500*a

a = 100/500

a = 0.2 [m/s^2]

This would be a cold front that forms when a warm air mass meets the area of a cooler air mass, although it should be noted that this doesn't always feel "cold".

And air rifle pellet of mass 2 g Is fired into a block of modelling clay mounted on a model railway track. The trunk and modelli
Anna007 [38]

Answer:

0.0816 kgm/s

Explanation:

From the question,

Momentum of the pellet just before it hits the modelling clay is = (mass of the pellet+ mass of the truck clay)×initial velocity of pellet.

P =(M+m)u...................... Equation 1

Where P =  initial momentum of the pellet, m = mass of the pellet, u = initial speed of the pillet, M = mass of the truck

Given: m = 2 g = 2/1000 kg = 0.002 kg, u = 0.8 m/s, M = 0.1 kg

Substitute these values into equation 1

P = (0.002+0.1)0.8

P = (0.102)0.8

P = 0.0816 kgm/s
