Step-by-step explanation:
We have,
Mass of ball is 9 kg
Initial speed, u = 5 m/s
Final speed, v = -2 m/s (negative as it bounces off)
(a) The change in velocity of the bowling ball is :
(b) Change of momentum of the ball is :
|p| = 630 kg-m/s
(c) Impulse momentum theorem states that the change in momentum of the ball is equal to the impulse exerted on the ball. So, impulse is 630 kg-m/s.
(d) Impulse is also given by :
Answer:
$3.55
Step-by-step explanation:
You need to add 29% of $2.75 to $2.75.
That means the price will be 129% of $2.75.
129% of $2.75 =
= 1.29 * $2.75
= $3.55
Answer:
Step-by-step explanation:
(-1 -7)/(-5 + 5) = -8/0 = undefined
Answer:
False. These events are dependent.
Step-by-step explanation:
A represent the event "the first individual has diabetes."
B represent the event "the second individual has diabetes."
The probability that the second individual has diabetes changes according to the probability that the first individual has diabetes. Therefore these events are dependent.
Answer:
y=-1/4x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-8)/(-4-(-16))
m=-3/(-4+16)
m=-3/12
m=-1/4
y-y1=m(x-x1)
y-8=-1/4(x-(-16))
y-8=-1/4(x+16)
y-8=-1/4x-16/4
y-8=-1/4x-4
y=-1/4x-4+8
y=-1/4x+4
