Answer: 9.2 inches
Step-by-step explanation:
We know that the sports stadium is 180 ft tall and that in the scale model there is 2 in for every 30 ft. If we divide 180 by 39 we get 4.6. There is 2 in for every 30 ft, so the answer would be 4.6 x 2 or 9.2 in.
KE = 1/2mv^2
1/2(1622)(11.3)^2 = 103557 J when the car hits the tree.
But since the car came to a stop, there is no motion, no kinetic energy
Answer:
1.15m/s
Step-by-step explanation:
Given data
m1=0.025 kg
m2= 2.35kg
u1= 217 m/s
v1= 109 m/s
u2= 0
v2=???
Applying the law of conservation of linear momentum
m1u1+m2u2=m1v1+m2v2
substitute
0.025*217+2.35*0= 0.025*109+2.35*v2
5.425= 2.725+ 2.35v2
5.425-2.725=2.35v2
2.7=2.35v2
divide both sides by 2.35
v2= 2.7/2.35
v2=1.15 m/s
Hence the speed of the watermelon will be 1.15m/s
Answer:
I think it's C
Step-by-step explanation:
Because the line is straight up and it on -2
Hope this helps if it's wrong i'm sorry but i hope it's right.:)
2x+6-4=0
First combine like terms:
2x+2=0
Then subtract +2 from both sides:
2x+2=0
-2. -2
Now: 2x=-2
After that you divide both sides by positive 2
And X= -1
