A car travels a displacement of 298 m North in a time of 12.7 s. Calculate the average velocity of the car. a. 0.043 m/s South
b. 0.043 m/s North
c. 23.5 m/s North

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 ima (higher than 1m) will be greater than the ima with the height of 1m.
