Which object has the least momentum? object a: m = 1 kg, v = 100 m/s object b: m = 10 kg, v = 12 m/s object c: m = 0.5 kg, v = 1

nirvana33 [79]

A = 1*100 = 100 Ns
b = 10 * 12 = 120 Ns
c = 0.5*1000 = 500 Ns
d = 100 * 2 = 200 Ns

a has least momentum

describe how a physical property, such as mass or texture, can change without causing a change in the substance

kari74 [83]

On the mass subject you could simply change the weight, on the texture subject you could smooth it out like polishing fresh wood, or you could change the color of water with a drink-mix packet. Hope it helped!

If I walk 15 minutes miles north and then 20 miles South:

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the Concept of the Kinematics.

1.) Distance travelled = 15+20 = 35 miles.

Ai the total distance covered is 35 miles.

2.) Displacement is the shortest distance from the initial point to the final point.

here it's ==> 20-15 = 5 miles

hence, displacement = 5 miles

Ms. Paul is standing at the top of a cliff that is 100 m tall. She kicks a rock and it gets a horizontal velocity of 15.0 m/s. D

Lynna [10]

vertical motion

h=1/2 gt²

100 = 1/2 x 10 x t²

t² = 100/5 = 20

t = 2√5 s

horizontal motion

x = v.t

x = 15 x 2√5

x = 30√5 m
