Their momentum would be equal. so, 
m1v1 = m2v2
0.25 * v1 = 0.05 * 500
v1 = 25 / 0.25
v1 = 100 m/s

In short, Your Answer would be 100 m/s

Hope this helps!

Solve using substitution method. 3×-4y=18 and 2x + y = 1
Shalnov [3]
3x - 4y = 18 ⇒ 3x -  4y = 18
2x +  y =   1 ⇒ 8x + 4y =   4
                              11x = 22
                               11     11
                                  x = 2
                          2x + y = 1
                       2(2) + y = 1
                           4 + y = 1
                         - 4        - 4
                                 y = -3
                            (x, y) = (2, 3)

Petra was given 12 yards of fabric to make costumes for the school play if each costume requires 1 1/2 yards how many costumes c
solmaris [256]

Petra can make 8 costumes with 12 yards of fabric

<h3><u>Solution:</u></h3>

Given that Petra was given 12 yards of fabric to make costumes for the school play

Each costume requires 1\frac{1}{2} yards

<em><u>To find: number of costume Petra can make</u></em>

The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

\text {number of costume Petra can make }=\frac{\text {total fabric she has }}{\text {fabric needed for one costume }}

Total fabric she has = 12 yards

Fabric needed for 1 costume = 1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2} yards

Therefore,

\text {number of costume Petra can make }=\frac{12}{3 / 2}=\frac{12}{3} \times 2=8

Thus petra can make 8 costumes with 12 yards of fabric
