Answer:

4 Newtons

Explanation:

  • I think it's 4 because mechanical advantage = output force/input force
  • So, it would be 60/15, which is 4 newtons

The mass of M1 = 12 Daltons and it has a speed of v1 = 200 m/s. The mass of M2 = 4 Daltons. What was the total momentum of the s
svet-max [94.6K]

Answer:

The total momentum is  p__{T }} =(2400  -4 v_2) \ Dalton \cdot m/s

Explanation:

The diagram illustration this  system is shown on the first uploaded image (From physics animation)

From the question we are told that

     The mass of the first object is M_1 =  12 \ Dalton

      The speed of the first mass is v_1 =  200 \ m/s

      The mass of the second object is  M_2 =  4 \ Dalton

      The speed of the second object is  assumed to be  - v_2

The total momentum of the system is the combined momentum of both object which is mathematically represented as

           p__{T }} = M_1 v_1 + M_2 v_2

   substituting values

            p__{T }} = 12 * 200 + 4 * (-v_2)

            p__{T }} =(2400  -4 v_2) \ Dalton \cdot m/s

A Jeep accelerated at 2.2 m/s2 until after 18 seconds its displacement was 660 meters. Assuming the Jeep traveled in a straight
pogonyaev
Ok so we know:
The time (t) is 18seconds
The acceleration (a) is 2.2m/s2
The displacement (r) is 660

Using the equation
r = ut +  \frac{1}{2} a {t}^{2}
With 'u' being the initial velocity we want, we get:
660 = 18u + 356.4
So:
18u = 303.6
So:
u = 16.8666
So the original/initial velocity was 16.8666 or 16.87 m/s

Hope this helped
