A 3-kilogram ball is accelerated from rest to a speed of 10 m/sec. What is the ball's change in momentum?

Answer

The change in momentum of ball is 30kg m/sec .

Explanation:

Formula for change in momentum is given by .

\Delta P = mv -mu

Where m is mass , v is final velocity and u is initial velocity .

As given

A 3-kilogram ball is accelerated from rest to a speed of 10 m/sec.

m = 3

u = 0 m/sec

v = 10 m/sec

Putting values in the formula

\Delta P = 3\times 10 -3\times 0

\Delta P = 30\ kg\ m/sec

Therefore the change in momentum of ball is 30kg m/sec .

Change in Momentum =  mv - mu.

u = 0, v = 10 m/s.  Note ball accelerated from rest, so initial velocity = 0. u =0

Change in Momentum =  mv - mu = 3*10 - 3*0 =30.

Change in Momentum = 30 kgm/s.

How does the direction of acceleration compare with the direction of the net force that produces it
Novay_Z [31]

Answer:

Explanation:

The direction of the acceleration is in the same direction as the net force causing it.  F = ma is actually a vector equation in which f and a are both vectors and m is a scalar constant.

What is true of the moon's orbital and rotational periods?
Eddi Din [679]
The moon's orbital and rotational periods are identical or the same, I<span>ts rate of spin is done in unison with its rate of revolution (the time that is needed to complete one orbit). Thus, the moon rotates exactly once every time it circles the Earth.</span>

Un movil de masa 12Kg sobre el cual estan actuando varias fuerzas F_1=48N, F_2=60N y F_3=30N Calcular la aceleracion con la cual
Nikitich [7]

Answer:

Lamentablemente el problema está incompleto, pues no sabemos la dirección en la que se aplican las fuerzas. Por ello, voy a resolver el problema asumiendo dos casos. (abajo se puede ver una imagen donde se describe cada caso)

1) Todas las fuerzas están en la misma dirección.

Entonces la fuerza neta será la suma de las 3 fuerzas, entonces:

F = 48N + 60N + 30N = 138N

Y por la segunda ley de Newton sabemos que:

F = m*a

fuerza igual a masa por aceleración.

Entonces la aceleración está dada por:

a = F/m = 138N/12kg = 11.5 m/s^2

2) Segundo caso, suponemos que F1 es opuesta a F2 y F3

En este caso, la fuerza neta será:

F = F2 + F3 - F1 = 60N + 30N - 48N = 42N

En este caso, la aceleración será:

a = 42N/12kg = 3.5 m/s^2
