Draw a diagram to illustrate the problem as shown below.
Each ball has mass = m.
The initial velocity of the blue ball = u.
The initial velocity of the red ball = 0.
Initial total momentum is
P1 = m*u + m*0 = mu
Final momentum is
P2 = mv + 3mv = 4mv
Because momentum is conserved,
mu = 4mv
u = 4v
Answer:
The velocity of the blue ball before the collision is 4v.
Answer:
32 Foot long hot dogs
Step-by-step explanation:
A hot dog stand serves 3 regular hot dogs for every 2 foot long hot dogs. This means they sell 3+2 = 5 together.
If they sell 80 in one day, then you find how many of each by solving the equation 5x = 80.
5x = 80
x = 16.
So 3*16 is the number of regular which is 48.
So 2*16 is the number of foot long which is 32.
She can make a lot of different fruit salad. one type of fruit per salad, two type per salad, 3 types per salad, even all of them to make one fruit salad. But if I had to answer with a number, then I would say at about 11 at the least
