Actually you can't solve this. There is no solutions.
I'm doing geometry for credit advancement in Odysseyware. Brainly and Openstudy are saviors. Anyways. So, and irrational number can't be written as a fraction, but can be written as a decimal. An irrational number has endless non repeating number to the right of the decimal point. A rational number is a number that can be written in a ratio. Which in turn means it can be written as a fraction. Both number of the fraction (numerator and denominator) are whole numbers. Any whole number is a rational number. <span />
It would be 1 / (x + 2) (x - 4)
Answer:
V2=-20.0155m/s
Step-by-step explanation:
To answer this question we will use the principle of conservation of momentum which is
MtVt=M1V1+M2V2
1) let's find the initial velocity.
We will use,
v=a*t
v=10m/s2*2s = 20 m/s
d=vot+1/2*a*t2
d=0+1/2*10*4
d=20m
2) For the speed of the lighter piece we use,
v22=v12+2ad
0=v12+2*-9.81*(530-20)
v12=10006.2
v1=100.031m/s
3) Computing this in our conservation of momentum equation it will be-
MtVt=M1V1+M2V2
1500kg*20m/s=(1500*1/3)kg*100.031m/s + (1500*2/3)+V2
30000=50015.5+1000V2
Therefore V2=-20.0155m/s.
