Answer:
OHHH THE ANSWER IS 1 would be pie 7 and the last one is .9 ok thanks for 15 points
Step-by-step explanation:
STEP 1: GO GET A CALULATOR
STEP 2 GO F UR STEP SIS
2r + 2s = 50
2r - s = 17
-----------subtract
3s = 33
s = 11
2r - s = 17
2r - 11 = 17
2r = 28
r = 14
so r = 14 and s = 11
answer is C. r = 14, s = 11
Answer: the answer is “B”
Step-by-step explanation: answer is LETTER B
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 :
