Assuming that the acceleration of an object due to gravity is ag = 10 m/s2, it is possible to find the distance an object falls when dropped by using the equation ay = \frac{1}{2} ag t2. Using this value for gravity, how far would an object drop after 5.0 s? 105 m
125 m
135 m
115 m

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

c) up

hope this

um if your asking how to beat a level then that i can with that and how to fix your wii but other than that i can't u

the answer is the index of refraction of the second medium is higher. i just took the test.
