Answer:
she should beat a speed of v₂ = 6.04 m/s in order to win the competition
Step-by-step explanation:
Since the momentum p is defined as
p = m*v
where
m= mass of the ball
v= velocity of the ball
denoting 1 and 2 as the first and second bowler , then to reach the momentum of the first bowler
p₂=p₁
therefore
m₁*v₁ = m₂*v₂
v₂ = v₁ * (m₁/m₂)
replacing values
v₂ = v₁ * (m₁/m₂) =8.6 m/s * (4.5 kg/6.4 kg ball) = 6.04 m/s
then since the momentum p = m*v increases with increasing v (at constant m) , she should beat a speed of v₂ = 6.04 m/s in order to win the competition
Answer:
he earned $15 an hour
Step-by-step explanation: 15 multiplied by 2 is 30 and 30 times 10 gives you 300.
Answer:
1/6
Step-by-step explanation:
this seems too simple but...
6/6 would be all the cupcakes the whole
so if 5/6 are gone than
1/6 are left
Firstly, solve the inequality for y using subtraction:
y > -6 - 4x
Then plug in the x and y values from the answer until the inequality proves true:
-12 > -6 -4(1)
-12 > -10 (false)
Then the next choice:
-9 > -6 - 4(0)
-9 > -6 (false)
Next choice:
-1 > -6 -4(-1)
-1 > -6 + 4
-1 > -2 (true)
Therefore, C is the correct answer. Hope this helps and let me know if you need more help!
Answer:
11x-2
Step-by-step explanation:
(3x2 - 4x + 6) + (7x - 2) This is the breakdown. (6 4x + 6)= 4x. + (7x-2) = 11x-2
