Mrs. smith walks from her house 11.2 m to the grocer. then she walks from the grocer 5.7 m to the pet store. then she walks 32.7 m from the pet store to her daughter's house. mrs smith's house is directly 23.5 m away from her daughter's house. if the trip took 17 minutes what was the average velocity of mrs. smith?

x₀ = initial position of the Mrs. smith = 0 m

since Mrs. smith finally reach her daughter's house

x = final position of Mrs. smith = 23.5 m

d = displacement of Mrs. smith

displacement of Mrs. smith is given as

d = x - x₀

inserting the values

d = 23.5 - 0

d = 23.5 m

t = time of the trip = 17 min = 17 x 60 sec = 1020 sec

average velocity of Mrs. smith is given as

V = d/t

inserting the values

V = 23.5 /1020

V = 0.023 m/s

falling water hydro = water .. spectcular places these plants are

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
