Free fall (cw)
1. an object in free fall
a. experiences no air resistance.
b. undergoes a downward acceleration.
c. has an acceleration with a magnitude of 9.81 m/s2 near e
d. all of the above
2. an object in free fall
a. experiences an increase in speed of 9.81 m/s during ea

i believe your answer is d mgf2

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

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
