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
Well when ever you're doing order of operations you always use please excuse my dear aunt sally please means parentheses ALWAYS GO FIRST Excuse means experience which if there's no parentheses exponents go first to my name is multiplication after parentheses multiplication always go first if there's no parentheses dear means division after multiplication comes division on means addition but pretty much after the multiplication parentheses and the division you complete the rest of the problem using the left to right method now the answer to this problem is
The answer the the question is c
Answer:
Option (A) and Option (E)
Step-by-step explanation:
Length of a segment between two points and is given by,
Length =
Length of the segment between J(-8, 1) and K(-5, 5) will be,
JK =
JK =
JK = 5 units
Length of segment between the points P(2, 8) and Q(7, 3) will be,
PQ =
PQ =
PQ = units
Length of segment between the points S(-3, -10) and T(3, -2) will be,
ST =
ST =
ST = 10 units
Therefore, Option (A) and Option (E) are the correct options.
total cost = 6.25 + 0.25 x
15.75 - 6.25 = 0.25 x
9.5 = 0.25 x
x = 38 prints
