Answer:
20.55 miles per hour (rounded to the nearest hundredth)
Explanation:
Divide 104 by 5.06
20.55335968379447
Round to the nearest hundredth
20.55
This can also be 20.6
If you round to the nearest tenth

Answer:
55.897905
Explanation:
1 Newton in Earth gravity is the equivalent weight of 1/9.80665 kg on Earth
9.80665 times 5.7=55.897905

Short answer, 10kg, it must be the same mass as Ball 1
Long calculation to prove the answer:
M1 = Mass of Ball 1
M2 = Mass of Ball 2
U1 = Initial speed of Ball 1
U2 = Initial speed of Ball 2
V1 = Final speed of Ball 1
V2 = Final speed of Ball 2
M1U1 + M2U2 = M1V1 + M2V2
10 x 20 + M2 x 20 = 10 x 40 + M2 x 0
200 + 20M2 = 400
20M2 = 200
M2 = 200 / 20
M2 = <u>10 kg</u>
Alternatively you could say that because the velocity of ball 1 increased by the exact velocity of ball 2, their masses must be equal, so both ball 1 and 2 are 10 kg.
