1.What is the force of a ball with a mass of 5 N if it accelerates
at 10 m/s/s?
2.What is the mass of a man if he
accelerates at 42 m/s/s and has
a force of 112N?
3.What is the acceleration of a
cat if it has a mass of 8 kg and
hits the cat flap with a force of
65 N?

the amount of current in the coil

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 total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
