Answer:
combined velocity of the system = 0.033 m/s.
Step-by-step explanation:
taking the bullet and block as single system since there is no external force involved momentum is conserved .
initial momentum of the bullet = mv
where m is the mass of bullet and v is velocity of bullet.
and initial momentum of block = 0 since its velocity is 0.
therefore initial momentum of the system = mv
= 0.005×40
= 0.2
when the bullet stick of together with the block let the combined velocity of the system be V
therefore applying conservation of momentum
mv = (M+m)V
0.2=(6+0.005)V
therefore V = 0.033 m/s
Th answer would be 12% 250-220=30 and 30 is 12% of 250
(2,-4) is new reflected coordinates
Answer:
29/69 (= 0.42)
Step-by-step explanation:
there are several ways to do this, one way is to use fractions:
Expressing each decimal in improper fractions:
14.5 = 14 1/2 = 29/2
34.5 = 34 1/2 = 69/2
Hence,
14.5 ÷ 34.5
= 29/2 ÷ 69/2
= 29/2 x 2/69
= 29/69 (answer)
If you need the answer in decimal, you can use long division to do 29÷69 and you will get 0.42 (nearest hundredth)
