Calculate the magnitude of the linear momentum for the following cases. (a) a proton with mass 1.67 10-27 kg, moving with a speed of 5.10 106 m/s kg · m/s (b) a 15.0-g bullet moving with a speed of 480 m/s kg · m/s (c) a 72.5-kg sprinter running with a speed of 10.5 m/s kg · m/s (d) the earth (mass = 5.98 1024 kg) moving with an orbital speed equal to 2.98 104 m/s. kg · m/s

The linear momentum of an object is given by:

p = mv

where

m is the mass

v is the velocity

Let's apply this formula to the 4 cases:

a) proton

m = 1.67 10-27 kg

v = 5.10 10^6 m/s

Momentum:

(b) bullet

m = 15.0 g = 0.015 kg

v = 480 m/s

Momentum:

(c) Sprinter

m = 72.5 kg

v = 10.5 m/s

Momentum:

(d) Earth

m = 5.98 10^24 kg

v = 2.98 10^4 m/s

Momentum:

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
