When a balloon is warmed by a lamp it just pops
I'm pretty sure it would be gold
Answer:
1.512 m/s
Explanation:
M₁ = 10.5
M₂ = 61.5kg
v₁ = 8.85m/s
v₂ = ?
This question involves conservation of momentum and law of conservation of momentum states that, the total momentum of a system does not change before and after impact and it's always constant.
Momentum = mass * velocity = M*V
total momentum of the system before caught the ball = total momentum after he caught the ball.
M₁V₁ = M₂V₂
10.5 * 8.85 = 61.5 * V₂
V₂ = 92.925 / 61.5
V₂ = 1.5109m/s ≈ 1.512m/s
Density review

What is the density of a piece of wood that has a mass of 25.0 grams and a volume of 29.4 cm3? d = .85 g/cm3
A piece of wood that measures 3.0 cm by 6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood? Would the piece of wood float in water? (volume = L x W x H) d = 1.11 gm/cm3
These stars fuse helium into carbon just like the sun.
